Command
Summary
AcceptAddressTransferCommand

Accepts an Elastic IP address transfer. For more information, see Accept a transferred Elastic IP address  in the Amazon VPC User Guide.

AcceptCapacityReservationBillingOwnershipCommand

Accepts a request to assign billing of the available capacity of a shared Capacity Reservation to your account. For more information, see Billing assignment for shared Amazon EC2 Capacity Reservations .

AcceptReservedInstancesExchangeQuoteCommand

Accepts the Convertible Reserved Instance exchange quote described in the GetReservedInstancesExchangeQuote call.

AcceptTransitGatewayMulticastDomainAssociationsCommand

Accepts a request to associate subnets with a transit gateway multicast domain.

AcceptTransitGatewayPeeringAttachmentCommand

Accepts a transit gateway peering attachment request. The peering attachment must be in the pendingAcceptance state.

AcceptTransitGatewayVpcAttachmentCommand

Accepts a request to attach a VPC to a transit gateway.

The VPC attachment must be in the pendingAcceptance state. Use DescribeTransitGatewayVpcAttachments to view your pending VPC attachment requests. Use RejectTransitGatewayVpcAttachment to reject a VPC attachment request.

AcceptVpcEndpointConnectionsCommand

Accepts connection requests to your VPC endpoint service.

AcceptVpcPeeringConnectionCommand

Accept a VPC peering connection request. To accept a request, the VPC peering connection must be in the pending-acceptance state, and you must be the owner of the peer VPC. Use DescribeVpcPeeringConnections to view your outstanding VPC peering connection requests.

For an inter-Region VPC peering connection request, you must accept the VPC peering connection in the Region of the accepter VPC.

AdvertiseByoipCidrCommand

Advertises an IPv4 or IPv6 address range that is provisioned for use with your Amazon Web Services resources through bring your own IP addresses (BYOIP).

You can perform this operation at most once every 10 seconds, even if you specify different address ranges each time.

We recommend that you stop advertising the BYOIP CIDR from other locations when you advertise it from Amazon Web Services. To minimize down time, you can configure your Amazon Web Services resources to use an address from a BYOIP CIDR before it is advertised, and then simultaneously stop advertising it from the current location and start advertising it through Amazon Web Services.

It can take a few minutes before traffic to the specified addresses starts routing to Amazon Web Services because of BGP propagation delays.

To stop advertising the BYOIP CIDR, use WithdrawByoipCidr.

AllocateAddressCommand

Allocates an Elastic IP address to your Amazon Web Services account. After you allocate the Elastic IP address you can associate it with an instance or network interface. After you release an Elastic IP address, it is released to the IP address pool and can be allocated to a different Amazon Web Services account.

You can allocate an Elastic IP address from an address pool owned by Amazon Web Services or from an address pool created from a public IPv4 address range that you have brought to Amazon Web Services for use with your Amazon Web Services resources using bring your own IP addresses (BYOIP). For more information, see Bring Your Own IP Addresses (BYOIP)  in the Amazon EC2 User Guide.

If you release an Elastic IP address, you might be able to recover it. You cannot recover an Elastic IP address that you released after it is allocated to another Amazon Web Services account. To attempt to recover an Elastic IP address that you released, specify it in this operation.

For more information, see Elastic IP Addresses  in the Amazon EC2 User Guide.

You can allocate a carrier IP address which is a public IP address from a telecommunication carrier, to a network interface which resides in a subnet in a Wavelength Zone (for example an EC2 instance).

AllocateHostsCommand

Allocates a Dedicated Host to your account. At a minimum, specify the supported instance type or instance family, the Availability Zone in which to allocate the host, and the number of hosts to allocate.

AllocateIpamPoolCidrCommand

Allocate a CIDR from an IPAM pool. The Region you use should be the IPAM pool locale. The locale is the Amazon Web Services Region where this IPAM pool is available for allocations.

In IPAM, an allocation is a CIDR assignment from an IPAM pool to another IPAM pool or to a resource. For more information, see Allocate CIDRs  in the Amazon VPC IPAM User Guide.

This action creates an allocation with strong consistency. The returned CIDR will not overlap with any other allocations from the same pool.

ApplySecurityGroupsToClientVpnTargetNetworkCommand

Applies a security group to the association between the target network and the Client VPN endpoint. This action replaces the existing security groups with the specified security groups.

AssignIpv6AddressesCommand

Assigns the specified IPv6 addresses to the specified network interface. You can specify specific IPv6 addresses, or you can specify the number of IPv6 addresses to be automatically assigned from the subnet's IPv6 CIDR block range. You can assign as many IPv6 addresses to a network interface as you can assign private IPv4 addresses, and the limit varies by instance type.

You must specify either the IPv6 addresses or the IPv6 address count in the request.

You can optionally use Prefix Delegation on the network interface. You must specify either the IPV6 Prefix Delegation prefixes, or the IPv6 Prefix Delegation count. For information, see Assigning prefixes to network interfaces  in the Amazon EC2 User Guide.

AssignPrivateIpAddressesCommand

Assigns the specified secondary private IP addresses to the specified network interface.

You can specify specific secondary IP addresses, or you can specify the number of secondary IP addresses to be automatically assigned from the subnet's CIDR block range. The number of secondary IP addresses that you can assign to an instance varies by instance type. For more information about Elastic IP addresses, see Elastic IP Addresses  in the Amazon EC2 User Guide.

When you move a secondary private IP address to another network interface, any Elastic IP address that is associated with the IP address is also moved.

Remapping an IP address is an asynchronous operation. When you move an IP address from one network interface to another, check network/interfaces/macs/mac/local-ipv4s in the instance metadata to confirm that the remapping is complete.

You must specify either the IP addresses or the IP address count in the request.

You can optionally use Prefix Delegation on the network interface. You must specify either the IPv4 Prefix Delegation prefixes, or the IPv4 Prefix Delegation count. For information, see Assigning prefixes to network interfaces  in the Amazon EC2 User Guide.

AssignPrivateNatGatewayAddressCommand

Assigns private IPv4 addresses to a private NAT gateway. For more information, see Work with NAT gateways  in the Amazon VPC User Guide.

AssociateAddressCommand

Associates an Elastic IP address, or carrier IP address (for instances that are in subnets in Wavelength Zones) with an instance or a network interface. Before you can use an Elastic IP address, you must allocate it to your account.

If the Elastic IP address is already associated with a different instance, it is disassociated from that instance and associated with the specified instance. If you associate an Elastic IP address with an instance that has an existing Elastic IP address, the existing address is disassociated from the instance, but remains allocated to your account.

[Subnets in Wavelength Zones] You can associate an IP address from the telecommunication carrier to the instance or network interface.

You cannot associate an Elastic IP address with an interface in a different network border group.

This is an idempotent operation. If you perform the operation more than once, Amazon EC2 doesn't return an error, and you may be charged for each time the Elastic IP address is remapped to the same instance. For more information, see the Elastic IP Addresses section of Amazon EC2 Pricing .

AssociateCapacityReservationBillingOwnerCommand

Initiates a request to assign billing of the unused capacity of a shared Capacity Reservation to a consumer account that is consolidated under the same Amazon Web Services organizations payer account. For more information, see Billing assignment for shared Amazon EC2 Capacity Reservations .

AssociateClientVpnTargetNetworkCommand

Associates a target network with a Client VPN endpoint. A target network is a subnet in a VPC. You can associate multiple subnets from the same VPC with a Client VPN endpoint. You can associate only one subnet in each Availability Zone. We recommend that you associate at least two subnets to provide Availability Zone redundancy.

If you specified a VPC when you created the Client VPN endpoint or if you have previous subnet associations, the specified subnet must be in the same VPC. To specify a subnet that's in a different VPC, you must first modify the Client VPN endpoint (ModifyClientVpnEndpoint) and change the VPC that's associated with it.

AssociateDhcpOptionsCommand

Associates a set of DHCP options (that you've previously created) with the specified VPC, or associates no DHCP options with the VPC.

After you associate the options with the VPC, any existing instances and all new instances that you launch in that VPC use the options. You don't need to restart or relaunch the instances. They automatically pick up the changes within a few hours, depending on how frequently the instance renews its DHCP lease. You can explicitly renew the lease using the operating system on the instance.

For more information, see DHCP option sets  in the Amazon VPC User Guide.

AssociateEnclaveCertificateIamRoleCommand

Associates an Identity and Access Management (IAM) role with an Certificate Manager (ACM) certificate. This enables the certificate to be used by the ACM for Nitro Enclaves application inside an enclave. For more information, see Certificate Manager for Nitro Enclaves  in the Amazon Web Services Nitro Enclaves User Guide.

When the IAM role is associated with the ACM certificate, the certificate, certificate chain, and encrypted private key are placed in an Amazon S3 location that only the associated IAM role can access. The private key of the certificate is encrypted with an Amazon Web Services managed key that has an attached attestation-based key policy.

To enable the IAM role to access the Amazon S3 object, you must grant it permission to call s3:GetObject on the Amazon S3 bucket returned by the command. To enable the IAM role to access the KMS key, you must grant it permission to call kms:Decrypt on the KMS key returned by the command. For more information, see Grant the role permission to access the certificate and encryption key  in the Amazon Web Services Nitro Enclaves User Guide.

AssociateIamInstanceProfileCommand

Associates an IAM instance profile with a running or stopped instance. You cannot associate more than one IAM instance profile with an instance.

AssociateInstanceEventWindowCommand

Associates one or more targets with an event window. Only one type of target (instance IDs, Dedicated Host IDs, or tags) can be specified with an event window.

For more information, see Define event windows for scheduled events  in the Amazon EC2 User Guide.

AssociateIpamByoasnCommand

Associates your Autonomous System Number (ASN) with a BYOIP CIDR that you own in the same Amazon Web Services Region. For more information, see Tutorial: Bring your ASN to IPAM  in the Amazon VPC IPAM guide.

After the association succeeds, the ASN is eligible for advertisement. You can view the association with DescribeByoipCidrs . You can advertise the CIDR with AdvertiseByoipCidr .

AssociateIpamResourceDiscoveryCommand

Associates an IPAM resource discovery with an Amazon VPC IPAM. A resource discovery is an IPAM component that enables IPAM to manage and monitor resources that belong to the owning account.

AssociateNatGatewayAddressCommand

Associates Elastic IP addresses (EIPs) and private IPv4 addresses with a public NAT gateway. For more information, see Work with NAT gateways  in the Amazon VPC User Guide.

By default, you can associate up to 2 Elastic IP addresses per public NAT gateway. You can increase the limit by requesting a quota adjustment. For more information, see Elastic IP address quotas  in the Amazon VPC User Guide.

When you associate an EIP or secondary EIPs with a public NAT gateway, the network border group of the EIPs must match the network border group of the Availability Zone (AZ) that the public NAT gateway is in. If it's not the same, the EIP will fail to associate. You can see the network border group for the subnet's AZ by viewing the details of the subnet. Similarly, you can view the network border group of an EIP by viewing the details of the EIP address. For more information about network border groups and EIPs, see Allocate an Elastic IP address  in the Amazon VPC User Guide.

AssociateRouteTableCommand

Associates a subnet in your VPC or an internet gateway or virtual private gateway attached to your VPC with a route table in your VPC. This association causes traffic from the subnet or gateway to be routed according to the routes in the route table. The action returns an association ID, which you need in order to disassociate the route table later. A route table can be associated with multiple subnets.

For more information, see Route tables  in the Amazon VPC User Guide.

AssociateSecurityGroupVpcCommand

Associates a security group with another VPC in the same Region. This enables you to use the same security group with network interfaces and instances in the specified VPC.

  • The VPC you want to associate the security group with must be in the same Region.

  • You can associate the security group with another VPC if your account owns the VPC or if the VPC was shared with you.

  • You must own the security group and the VPC that it was created in.

  • You cannot use this feature with default security groups.

  • You cannot use this feature with the default VPC.

AssociateSubnetCidrBlockCommand

Associates a CIDR block with your subnet. You can only associate a single IPv6 CIDR block with your subnet.

AssociateTransitGatewayMulticastDomainCommand

Associates the specified subnets and transit gateway attachments with the specified transit gateway multicast domain.

The transit gateway attachment must be in the available state before you can add a resource. Use DescribeTransitGatewayAttachments  to see the state of the attachment.

AssociateTransitGatewayPolicyTableCommand

Associates the specified transit gateway attachment with a transit gateway policy table.

AssociateTransitGatewayRouteTableCommand

Associates the specified attachment with the specified transit gateway route table. You can associate only one route table with an attachment.

AssociateTrunkInterfaceCommand

Associates a branch network interface with a trunk network interface.

Before you create the association, use CreateNetworkInterface  command and set the interface type to trunk. You must also create a network interface for each branch network interface that you want to associate with the trunk network interface.

AssociateVpcCidrBlockCommand

Associates a CIDR block with your VPC. You can associate a secondary IPv4 CIDR block, an Amazon-provided IPv6 CIDR block, or an IPv6 CIDR block from an IPv6 address pool that you provisioned through bring your own IP addresses (BYOIP ).

You must specify one of the following in the request: an IPv4 CIDR block, an IPv6 pool, or an Amazon-provided IPv6 CIDR block.

For more information about associating CIDR blocks with your VPC and applicable restrictions, see IP addressing for your VPCs and subnets  in the Amazon VPC User Guide.

AttachClassicLinkVpcCommand

This action is deprecated.

Links an EC2-Classic instance to a ClassicLink-enabled VPC through one or more of the VPC security groups. You cannot link an EC2-Classic instance to more than one VPC at a time. You can only link an instance that's in the running state. An instance is automatically unlinked from a VPC when it's stopped - you can link it to the VPC again when you restart it.

After you've linked an instance, you cannot change the VPC security groups that are associated with it. To change the security groups, you must first unlink the instance, and then link it again.

Linking your instance to a VPC is sometimes referred to as attaching your instance.

AttachInternetGatewayCommand

Attaches an internet gateway or a virtual private gateway to a VPC, enabling connectivity between the internet and the VPC. For more information, see Internet gateways  in the Amazon VPC User Guide.

AttachNetworkInterfaceCommand

Attaches a network interface to an instance.

AttachVerifiedAccessTrustProviderCommand

Attaches the specified Amazon Web Services Verified Access trust provider to the specified Amazon Web Services Verified Access instance.

AttachVolumeCommand

Attaches an EBS volume to a running or stopped instance and exposes it to the instance with the specified device name.

Encrypted EBS volumes must be attached to instances that support Amazon EBS encryption. For more information, see Amazon EBS encryption  in the Amazon EBS User Guide.

After you attach an EBS volume, you must make it available. For more information, see Make an EBS volume available for use .

If a volume has an Amazon Web Services Marketplace product code:

  • The volume can be attached only to a stopped instance.

  • Amazon Web Services Marketplace product codes are copied from the volume to the instance.

  • You must be subscribed to the product.

  • The instance type and operating system of the instance must support the product. For example, you can't detach a volume from a Windows instance and attach it to a Linux instance.

For more information, see Attach an Amazon EBS volume to an instance  in the Amazon EBS User Guide.

AttachVpnGatewayCommand

Attaches an available virtual private gateway to a VPC. You can attach one virtual private gateway to one VPC at a time.

For more information, see Amazon Web Services Site-to-Site VPN  in the Amazon Web Services Site-to-Site VPN User Guide.

AuthorizeClientVpnIngressCommand

Adds an ingress authorization rule to a Client VPN endpoint. Ingress authorization rules act as firewall rules that grant access to networks. You must configure ingress authorization rules to enable clients to access resources in Amazon Web Services or on-premises networks.

AuthorizeSecurityGroupEgressCommand

Adds the specified outbound (egress) rules to a security group.

An outbound rule permits instances to send traffic to the specified IPv4 or IPv6 address ranges, the IP address ranges specified by a prefix list, or the instances that are associated with a source security group. For more information, see Security group rules .

You must specify exactly one of the following destinations: an IPv4 or IPv6 address range, a prefix list, or a security group. You must specify a protocol for each rule (for example, TCP). If the protocol is TCP or UDP, you must also specify a port or port range. If the protocol is ICMP or ICMPv6, you must also specify the ICMP type and code.

Rule changes are propagated to instances associated with the security group as quickly as possible. However, a small delay might occur.

For examples of rules that you can add to security groups for specific access scenarios, see Security group rules for different use cases  in the Amazon EC2 User Guide.

For information about security group quotas, see Amazon VPC quotas  in the Amazon VPC User Guide.

AuthorizeSecurityGroupIngressCommand

Adds the specified inbound (ingress) rules to a security group.

An inbound rule permits instances to receive traffic from the specified IPv4 or IPv6 address range, the IP address ranges that are specified by a prefix list, or the instances that are associated with a destination security group. For more information, see Security group rules .

You must specify exactly one of the following sources: an IPv4 or IPv6 address range, a prefix list, or a security group. You must specify a protocol for each rule (for example, TCP). If the protocol is TCP or UDP, you must also specify a port or port range. If the protocol is ICMP or ICMPv6, you must also specify the ICMP/ICMPv6 type and code.

Rule changes are propagated to instances associated with the security group as quickly as possible. However, a small delay might occur.

For examples of rules that you can add to security groups for specific access scenarios, see Security group rules for different use cases  in the Amazon EC2 User Guide.

For more information about security group quotas, see Amazon VPC quotas  in the Amazon VPC User Guide.

BundleInstanceCommand

Bundles an Amazon instance store-backed Windows instance.

During bundling, only the root device volume (C:) is bundled. Data on other instance store volumes is not preserved.

This action is not applicable for Linux/Unix instances or Windows instances that are backed by Amazon EBS.

CancelBundleTaskCommand

Cancels a bundling operation for an instance store-backed Windows instance.

CancelCapacityReservationCommand

Cancels the specified Capacity Reservation, releases the reserved capacity, and changes the Capacity Reservation's state to cancelled.

You can cancel a Capacity Reservation that is in the following states:

  • assessing

  • active and there is no commitment duration or the commitment duration has elapsed. You can't cancel a future-dated Capacity Reservation during the commitment duration.

You can't modify or cancel a Capacity Block. For more information, see Capacity Blocks for ML .

If a future-dated Capacity Reservation enters the delayed state, the commitment duration is waived, and you can cancel it as soon as it enters the active state.

Instances running in the reserved capacity continue running until you stop them. Stopped instances that target the Capacity Reservation can no longer launch. Modify these instances to either target a different Capacity Reservation, launch On-Demand Instance capacity, or run in any open Capacity Reservation that has matching attributes and sufficient capacity.

CancelCapacityReservationFleetsCommand

Cancels one or more Capacity Reservation Fleets. When you cancel a Capacity Reservation Fleet, the following happens:

  • The Capacity Reservation Fleet's status changes to cancelled.

  • The individual Capacity Reservations in the Fleet are cancelled. Instances running in the Capacity Reservations at the time of cancelling the Fleet continue to run in shared capacity.

  • The Fleet stops creating new Capacity Reservations.

CancelConversionTaskCommand

Cancels an active conversion task. The task can be the import of an instance or volume. The action removes all artifacts of the conversion, including a partially uploaded volume or instance. If the conversion is complete or is in the process of transferring the final disk image, the command fails and returns an exception.

CancelDeclarativePoliciesReportCommand

Cancels the generation of an account status report.

You can only cancel a report while it has the running status. Reports with other statuses (complete, cancelled, or error) can't be canceled.

For more information, see Generating the account status report for declarative policies  in the Amazon Web Services Organizations User Guide.

CancelExportTaskCommand

Cancels an active export task. The request removes all artifacts of the export, including any partially-created Amazon S3 objects. If the export task is complete or is in the process of transferring the final disk image, the command fails and returns an error.

CancelImageLaunchPermissionCommand

Removes your Amazon Web Services account from the launch permissions for the specified AMI. For more information, see Cancel having an AMI shared with your Amazon Web Services account  in the Amazon EC2 User Guide.

CancelImportTaskCommand

Cancels an in-process import virtual machine or import snapshot task.

CancelReservedInstancesListingCommand

Cancels the specified Reserved Instance listing in the Reserved Instance Marketplace.

For more information, see Sell in the Reserved Instance Marketplace  in the Amazon EC2 User Guide.

CancelSpotFleetRequestsCommand

Cancels the specified Spot Fleet requests.

After you cancel a Spot Fleet request, the Spot Fleet launches no new instances.

You must also specify whether a canceled Spot Fleet request should terminate its instances. If you choose to terminate the instances, the Spot Fleet request enters the cancelled_terminating state. Otherwise, the Spot Fleet request enters the cancelled_running state and the instances continue to run until they are interrupted or you terminate them manually.

Restrictions

  • You can delete up to 100 fleets in a single request. If you exceed the specified number, no fleets are deleted.

CancelSpotInstanceRequestsCommand

Cancels one or more Spot Instance requests.

Canceling a Spot Instance request does not terminate running Spot Instances associated with the request.

ConfirmProductInstanceCommand

Determines whether a product code is associated with an instance. This action can only be used by the owner of the product code. It is useful when a product code owner must verify whether another user's instance is eligible for support.

CopyFpgaImageCommand

Copies the specified Amazon FPGA Image (AFI) to the current Region.

CopyImageCommand

Initiates an AMI copy operation. You can copy an AMI from one Region to another, or from a Region to an Outpost. You can't copy an AMI from an Outpost to a Region, from one Outpost to another, or within the same Outpost. To copy an AMI to another partition, see CreateStoreImageTask .

When you copy an AMI from one Region to another, the destination Region is the current Region.

When you copy an AMI from a Region to an Outpost, specify the ARN of the Outpost as the destination. Backing snapshots copied to an Outpost are encrypted by default using the default encryption key for the Region or the key that you specify. Outposts do not support unencrypted snapshots.

For information about the prerequisites when copying an AMI, see Copy an AMI  in the Amazon EC2 User Guide.

CopySnapshotCommand

Copies a point-in-time snapshot of an EBS volume and stores it in Amazon S3. You can copy a snapshot within the same Region, from one Region to another, or from a Region to an Outpost. You can't copy a snapshot from an Outpost to a Region, from one Outpost to another, or within the same Outpost.

You can use the snapshot to create EBS volumes or Amazon Machine Images (AMIs).

When copying snapshots to a Region, copies of encrypted EBS snapshots remain encrypted. Copies of unencrypted snapshots remain unencrypted, unless you enable encryption for the snapshot copy operation. By default, encrypted snapshot copies use the default KMS key; however, you can specify a different KMS key. To copy an encrypted snapshot that has been shared from another account, you must have permissions for the KMS key used to encrypt the snapshot.

Snapshots copied to an Outpost are encrypted by default using the default encryption key for the Region, or a different key that you specify in the request using KmsKeyId. Outposts do not support unencrypted snapshots. For more information, see Amazon EBS local snapshots on Outposts  in the Amazon EBS User Guide.

Snapshots created by copying another snapshot have an arbitrary volume ID that should not be used for any purpose.

For more information, see Copy an Amazon EBS snapshot  in the Amazon EBS User Guide.

CreateCapacityReservationBySplittingCommand

Create a new Capacity Reservation by splitting the capacity of the source Capacity Reservation. The new Capacity Reservation will have the same attributes as the source Capacity Reservation except for tags. The source Capacity Reservation must be active and owned by your Amazon Web Services account.

CreateCapacityReservationCommand

Creates a new Capacity Reservation with the specified attributes. Capacity Reservations enable you to reserve capacity for your Amazon EC2 instances in a specific Availability Zone for any duration.

You can create a Capacity Reservation at any time, and you can choose when it starts. You can create a Capacity Reservation for immediate use or you can request a Capacity Reservation for a future date.

For more information, see Reserve compute capacity with On-Demand Capacity Reservations  in the Amazon EC2 User Guide.

Your request to create a Capacity Reservation could fail if:

  • Amazon EC2 does not have sufficient capacity. In this case, try again at a later time, try in a different Availability Zone, or request a smaller Capacity Reservation. If your workload is flexible across instance types and sizes, try with different instance attributes.

  • The requested quantity exceeds your On-Demand Instance quota. In this case, increase your On-Demand Instance quota for the requested instance type and try again. For more information, see Amazon EC2 Service Quotas  in the Amazon EC2 User Guide.

CreateCapacityReservationFleetCommand

Creates a Capacity Reservation Fleet. For more information, see Create a Capacity Reservation Fleet  in the Amazon EC2 User Guide.

CreateCarrierGatewayCommand

Creates a carrier gateway. For more information about carrier gateways, see Carrier gateways  in the Amazon Web Services Wavelength Developer Guide.

CreateClientVpnEndpointCommand

Creates a Client VPN endpoint. A Client VPN endpoint is the resource you create and configure to enable and manage client VPN sessions. It is the destination endpoint at which all client VPN sessions are terminated.

CreateClientVpnRouteCommand

Adds a route to a network to a Client VPN endpoint. Each Client VPN endpoint has a route table that describes the available destination network routes. Each route in the route table specifies the path for traffic to specific resources or networks.

CreateCoipCidrCommand

Creates a range of customer-owned IP addresses.

CreateCoipPoolCommand

Creates a pool of customer-owned IP (CoIP) addresses.

CreateCustomerGatewayCommand

Provides information to Amazon Web Services about your customer gateway device. The customer gateway device is the appliance at your end of the VPN connection. You must provide the IP address of the customer gateway device’s external interface. The IP address must be static and can be behind a device performing network address translation (NAT).

For devices that use Border Gateway Protocol (BGP), you can also provide the device's BGP Autonomous System Number (ASN). You can use an existing ASN assigned to your network. If you don't have an ASN already, you can use a private ASN. For more information, see Customer gateway options for your Site-to-Site VPN connection  in the Amazon Web Services Site-to-Site VPN User Guide.

To create more than one customer gateway with the same VPN type, IP address, and BGP ASN, specify a unique device name for each customer gateway. An identical request returns information about the existing customer gateway; it doesn't create a new customer gateway.

CreateDefaultSubnetCommand

Creates a default subnet with a size /20 IPv4 CIDR block in the specified Availability Zone in your default VPC. You can have only one default subnet per Availability Zone. For more information, see Create a default subnet  in the Amazon VPC User Guide.

CreateDefaultVpcCommand

Creates a default VPC with a size /16 IPv4 CIDR block and a default subnet in each Availability Zone. For more information about the components of a default VPC, see Default VPCs  in the Amazon VPC User Guide. You cannot specify the components of the default VPC yourself.

If you deleted your previous default VPC, you can create a default VPC. You cannot have more than one default VPC per Region.

CreateDhcpOptionsCommand

Creates a custom set of DHCP options. After you create a DHCP option set, you associate it with a VPC. After you associate a DHCP option set with a VPC, all existing and newly launched instances in the VPC use this set of DHCP options.

The following are the individual DHCP options you can specify. For more information, see DHCP option sets  in the Amazon VPC User Guide.

  • domain-name - If you're using AmazonProvidedDNS in us-east-1, specify ec2.internal. If you're using AmazonProvidedDNS in any other Region, specify region.compute.internal. Otherwise, specify a custom domain name. This value is used to complete unqualified DNS hostnames.

    Some Linux operating systems accept multiple domain names separated by spaces. However, Windows and other Linux operating systems treat the value as a single domain, which results in unexpected behavior. If your DHCP option set is associated with a VPC that has instances running operating systems that treat the value as a single domain, specify only one domain name.

  • domain-name-servers - The IP addresses of up to four DNS servers, or AmazonProvidedDNS. To specify multiple domain name servers in a single parameter, separate the IP addresses using commas. To have your instances receive custom DNS hostnames as specified in domain-name, you must specify a custom DNS server.

  • ntp-servers - The IP addresses of up to eight Network Time Protocol (NTP) servers (four IPv4 addresses and four IPv6 addresses).

  • netbios-name-servers - The IP addresses of up to four NetBIOS name servers.

  • netbios-node-type - The NetBIOS node type (1, 2, 4, or 8). We recommend that you specify 2. Broadcast and multicast are not supported. For more information about NetBIOS node types, see RFC 2132 .

  • ipv6-address-preferred-lease-time - A value (in seconds, minutes, hours, or years) for how frequently a running instance with an IPv6 assigned to it goes through DHCPv6 lease renewal. Acceptable values are between 140 and 2147483647 seconds (approximately 68 years). If no value is entered, the default lease time is 140 seconds. If you use long-term addressing for EC2 instances, you can increase the lease time and avoid frequent lease renewal requests. Lease renewal typically occurs when half of the lease time has elapsed.

CreateEgressOnlyInternetGatewayCommand

[IPv6 only] Creates an egress-only internet gateway for your VPC. An egress-only internet gateway is used to enable outbound communication over IPv6 from instances in your VPC to the internet, and prevents hosts outside of your VPC from initiating an IPv6 connection with your instance.

CreateFleetCommand

Creates an EC2 Fleet that contains the configuration information for On-Demand Instances and Spot Instances. Instances are launched immediately if there is available capacity.

A single EC2 Fleet can include multiple launch specifications that vary by instance type, AMI, Availability Zone, or subnet.

For more information, see EC2 Fleet  in the Amazon EC2 User Guide.

CreateFlowLogsCommand

Creates one or more flow logs to capture information about IP traffic for a specific network interface, subnet, or VPC.

Flow log data for a monitored network interface is recorded as flow log records, which are log events consisting of fields that describe the traffic flow. For more information, see Flow log records  in the Amazon VPC User Guide.

When publishing to CloudWatch Logs, flow log records are published to a log group, and each network interface has a unique log stream in the log group. When publishing to Amazon S3, flow log records for all of the monitored network interfaces are published to a single log file object that is stored in the specified bucket.

For more information, see VPC Flow Logs  in the Amazon VPC User Guide.

CreateFpgaImageCommand

Creates an Amazon FPGA Image (AFI) from the specified design checkpoint (DCP).

The create operation is asynchronous. To verify that the AFI is ready for use, check the output logs.

An AFI contains the FPGA bitstream that is ready to download to an FPGA. You can securely deploy an AFI on multiple FPGA-accelerated instances. For more information, see the Amazon Web Services FPGA Hardware Development Kit .

CreateImageCommand

Creates an Amazon EBS-backed AMI from an Amazon EBS-backed instance that is either running or stopped.

If you customized your instance with instance store volumes or Amazon EBS volumes in addition to the root device volume, the new AMI contains block device mapping information for those volumes. When you launch an instance from this new AMI, the instance automatically launches with those additional volumes.

For more information, see Create an Amazon EBS-backed Linux AMI  in the Amazon Elastic Compute Cloud User Guide.

CreateInstanceConnectEndpointCommand

Creates an EC2 Instance Connect Endpoint.

An EC2 Instance Connect Endpoint allows you to connect to an instance, without requiring the instance to have a public IPv4 address. For more information, see Connect to your instances without requiring a public IPv4 address using EC2 Instance Connect Endpoint  in the Amazon EC2 User Guide.

CreateInstanceEventWindowCommand

Creates an event window in which scheduled events for the associated Amazon EC2 instances can run.

You can define either a set of time ranges or a cron expression when creating the event window, but not both. All event window times are in UTC.

You can create up to 200 event windows per Amazon Web Services Region.

When you create the event window, targets (instance IDs, Dedicated Host IDs, or tags) are not yet associated with it. To ensure that the event window can be used, you must associate one or more targets with it by using the AssociateInstanceEventWindow API.

Event windows are applicable only for scheduled events that stop, reboot, or terminate instances.

Event windows are not applicable for:

  • Expedited scheduled events and network maintenance events.

  • Unscheduled maintenance such as AutoRecovery and unplanned reboots.

For more information, see Define event windows for scheduled events  in the Amazon EC2 User Guide.

CreateInstanceExportTaskCommand

Exports a running or stopped instance to an Amazon S3 bucket.

For information about the prerequisites for your Amazon S3 bucket, supported operating systems, image formats, and known limitations for the types of instances you can export, see Exporting an instance as a VM Using VM Import/Export  in the VM Import/Export User Guide.

CreateInternetGatewayCommand

Creates an internet gateway for use with a VPC. After creating the internet gateway, you attach it to a VPC using AttachInternetGateway.

For more information, see Internet gateways  in the Amazon VPC User Guide.

CreateIpamCommand

Create an IPAM. Amazon VPC IP Address Manager (IPAM) is a VPC feature that you can use to automate your IP address management workflows including assigning, tracking, troubleshooting, and auditing IP addresses across Amazon Web Services Regions and accounts throughout your Amazon Web Services Organization.

For more information, see Create an IPAM  in the Amazon VPC IPAM User Guide.

CreateIpamExternalResourceVerificationTokenCommand

Create a verification token. A verification token is an Amazon Web Services-generated random value that you can use to prove ownership of an external resource. For example, you can use a verification token to validate that you control a public IP address range when you bring an IP address range to Amazon Web Services (BYOIP).

CreateIpamPoolCommand

Create an IP address pool for Amazon VPC IP Address Manager (IPAM). In IPAM, a pool is a collection of contiguous IP addresses CIDRs. Pools enable you to organize your IP addresses according to your routing and security needs. For example, if you have separate routing and security needs for development and production applications, you can create a pool for each.

For more information, see Create a top-level pool  in the Amazon VPC IPAM User Guide.

CreateIpamResourceDiscoveryCommand

Creates an IPAM resource discovery. A resource discovery is an IPAM component that enables IPAM to manage and monitor resources that belong to the owning account.

CreateIpamScopeCommand

Create an IPAM scope. In IPAM, a scope is the highest-level container within IPAM. An IPAM contains two default scopes. Each scope represents the IP space for a single network. The private scope is intended for all private IP address space. The public scope is intended for all public IP address space. Scopes enable you to reuse IP addresses across multiple unconnected networks without causing IP address overlap or conflict.

For more information, see Add a scope  in the Amazon VPC IPAM User Guide.

CreateKeyPairCommand

Creates an ED25519 or 2048-bit RSA key pair with the specified name and in the specified format. Amazon EC2 stores the public key and displays the private key for you to save to a file. The private key is returned as an unencrypted PEM encoded PKCS#1 private key or an unencrypted PPK formatted private key for use with PuTTY. If a key with the specified name already exists, Amazon EC2 returns an error.

The key pair returned to you is available only in the Amazon Web Services Region in which you create it. If you prefer, you can create your own key pair using a third-party tool and upload it to any Region using ImportKeyPair.

You can have up to 5,000 key pairs per Amazon Web Services Region.

For more information, see Amazon EC2 key pairs  in the Amazon EC2 User Guide.

CreateLaunchTemplateCommand

Creates a launch template.

A launch template contains the parameters to launch an instance. When you launch an instance using RunInstances, you can specify a launch template instead of providing the launch parameters in the request. For more information, see Launch an instance from a launch template  in the Amazon EC2 User Guide.

To clone an existing launch template as the basis for a new launch template, use the Amazon EC2 console. The API, SDKs, and CLI do not support cloning a template. For more information, see Create a launch template from an existing launch template  in the Amazon EC2 User Guide.

CreateLaunchTemplateVersionCommand

Creates a new version of a launch template. You must specify an existing launch template, either by name or ID. You can determine whether the new version inherits parameters from a source version, and add or overwrite parameters as needed.

Launch template versions are numbered in the order in which they are created. You can't specify, change, or replace the numbering of launch template versions.

Launch templates are immutable; after you create a launch template, you can't modify it. Instead, you can create a new version of the launch template that includes the changes that you require.

For more information, see Modify a launch template (manage launch template versions)  in the Amazon EC2 User Guide.

CreateLocalGatewayRouteCommand

Creates a static route for the specified local gateway route table. You must specify one of the following targets:

  • LocalGatewayVirtualInterfaceGroupId

  • NetworkInterfaceId

CreateLocalGatewayRouteTableCommand

Creates a local gateway route table.

CreateLocalGatewayRouteTableVirtualInterfaceGroupAssociationCommand

Creates a local gateway route table virtual interface group association.

CreateLocalGatewayRouteTableVpcAssociationCommand

Associates the specified VPC with the specified local gateway route table.

CreateManagedPrefixListCommand

Creates a managed prefix list. You can specify entries for the prefix list. Each entry consists of a CIDR block and an optional description.

CreateNatGatewayCommand

Creates a NAT gateway in the specified subnet. This action creates a network interface in the specified subnet with a private IP address from the IP address range of the subnet. You can create either a public NAT gateway or a private NAT gateway.

With a public NAT gateway, internet-bound traffic from a private subnet can be routed to the NAT gateway, so that instances in a private subnet can connect to the internet.

With a private NAT gateway, private communication is routed across VPCs and on-premises networks through a transit gateway or virtual private gateway. Common use cases include running large workloads behind a small pool of allowlisted IPv4 addresses, preserving private IPv4 addresses, and communicating between overlapping networks.

For more information, see NAT gateways  in the Amazon VPC User Guide.

When you create a public NAT gateway and assign it an EIP or secondary EIPs, the network border group of the EIPs must match the network border group of the Availability Zone (AZ) that the public NAT gateway is in. If it's not the same, the NAT gateway will fail to launch. You can see the network border group for the subnet's AZ by viewing the details of the subnet. Similarly, you can view the network border group of an EIP by viewing the details of the EIP address. For more information about network border groups and EIPs, see Allocate an Elastic IP address  in the Amazon VPC User Guide.

CreateNetworkAclCommand

Creates a network ACL in a VPC. Network ACLs provide an optional layer of security (in addition to security groups) for the instances in your VPC.

For more information, see Network ACLs  in the Amazon VPC User Guide.

CreateNetworkAclEntryCommand

Creates an entry (a rule) in a network ACL with the specified rule number. Each network ACL has a set of numbered ingress rules and a separate set of numbered egress rules. When determining whether a packet should be allowed in or out of a subnet associated with the ACL, we process the entries in the ACL according to the rule numbers, in ascending order. Each network ACL has a set of ingress rules and a separate set of egress rules.

We recommend that you leave room between the rule numbers (for example, 100, 110, 120, ...), and not number them one right after the other (for example, 101, 102, 103, ...). This makes it easier to add a rule between existing ones without having to renumber the rules.

After you add an entry, you can't modify it; you must either replace it, or create an entry and delete the old one.

For more information about network ACLs, see Network ACLs  in the Amazon VPC User Guide.

CreateNetworkInsightsAccessScopeCommand

Creates a Network Access Scope.

Amazon Web Services Network Access Analyzer enables cloud networking and cloud operations teams to verify that their networks on Amazon Web Services conform to their network security and governance objectives. For more information, see the Amazon Web Services Network Access Analyzer Guide .

CreateNetworkInsightsPathCommand

Creates a path to analyze for reachability.

Reachability Analyzer enables you to analyze and debug network reachability between two resources in your virtual private cloud (VPC). For more information, see the Reachability Analyzer Guide .

CreateNetworkInterfaceCommand

Creates a network interface in the specified subnet.

The number of IP addresses you can assign to a network interface varies by instance type.

For more information about network interfaces, see Elastic network interfaces  in the Amazon EC2 User Guide.

CreateNetworkInterfacePermissionCommand

Grants an Amazon Web Services-authorized account permission to attach the specified network interface to an instance in their account.

You can grant permission to a single Amazon Web Services account only, and only one account at a time.

CreatePlacementGroupCommand

Creates a placement group in which to launch instances. The strategy of the placement group determines how the instances are organized within the group.

A cluster placement group is a logical grouping of instances within a single Availability Zone that benefit from low network latency, high network throughput. A spread placement group places instances on distinct hardware. A partition placement group places groups of instances in different partitions, where instances in one partition do not share the same hardware with instances in another partition.

For more information, see Placement groups  in the Amazon EC2 User Guide.

CreatePublicIpv4PoolCommand

Creates a public IPv4 address pool. A public IPv4 pool is an EC2 IP address pool required for the public IPv4 CIDRs that you own and bring to Amazon Web Services to manage with IPAM. IPv6 addresses you bring to Amazon Web Services, however, use IPAM pools only. To monitor the status of pool creation, use DescribePublicIpv4Pools .

CreateReplaceRootVolumeTaskCommand

Replaces the EBS-backed root volume for a running instance with a new volume that is restored to the original root volume's launch state, that is restored to a specific snapshot taken from the original root volume, or that is restored from an AMI that has the same key characteristics as that of the instance.

For more information, see Replace a root volume  in the Amazon EC2 User Guide.

CreateReservedInstancesListingCommand

Creates a listing for Amazon EC2 Standard Reserved Instances to be sold in the Reserved Instance Marketplace. You can submit one Standard Reserved Instance listing at a time. To get a list of your Standard Reserved Instances, you can use the DescribeReservedInstances operation.

Only Standard Reserved Instances can be sold in the Reserved Instance Marketplace. Convertible Reserved Instances cannot be sold.

The Reserved Instance Marketplace matches sellers who want to resell Standard Reserved Instance capacity that they no longer need with buyers who want to purchase additional capacity. Reserved Instances bought and sold through the Reserved Instance Marketplace work like any other Reserved Instances.

To sell your Standard Reserved Instances, you must first register as a seller in the Reserved Instance Marketplace. After completing the registration process, you can create a Reserved Instance Marketplace listing of some or all of your Standard Reserved Instances, and specify the upfront price to receive for them. Your Standard Reserved Instance listings then become available for purchase. To view the details of your Standard Reserved Instance listing, you can use the DescribeReservedInstancesListings operation.

For more information, see Sell in the Reserved Instance Marketplace  in the Amazon EC2 User Guide.

CreateRestoreImageTaskCommand

Starts a task that restores an AMI from an Amazon S3 object that was previously created by using CreateStoreImageTask .

To use this API, you must have the required permissions. For more information, see Permissions for storing and restoring AMIs using Amazon S3  in the Amazon EC2 User Guide.

For more information, see Store and restore an AMI using Amazon S3  in the Amazon EC2 User Guide.

CreateRouteCommand

Creates a route in a route table within a VPC.

You must specify either a destination CIDR block or a prefix list ID. You must also specify exactly one of the resources from the parameter list.

When determining how to route traffic, we use the route with the most specific match. For example, traffic is destined for the IPv4 address 192.0.2.3, and the route table includes the following two IPv4 routes:

  • 192.0.2.0/24 (goes to some target A)

  • 192.0.2.0/28 (goes to some target B)

Both routes apply to the traffic destined for 192.0.2.3. However, the second route in the list covers a smaller number of IP addresses and is therefore more specific, so we use that route to determine where to target the traffic.

For more information about route tables, see Route tables  in the Amazon VPC User Guide.

CreateRouteTableCommand

Creates a route table for the specified VPC. After you create a route table, you can add routes and associate the table with a subnet.

For more information, see Route tables  in the Amazon VPC User Guide.

CreateSecurityGroupCommand

Creates a security group.

A security group acts as a virtual firewall for your instance to control inbound and outbound traffic. For more information, see Amazon EC2 security groups  in the Amazon EC2 User Guide and Security groups for your VPC  in the Amazon VPC User Guide.

When you create a security group, you specify a friendly name of your choice. You can't have two security groups for the same VPC with the same name.

You have a default security group for use in your VPC. If you don't specify a security group when you launch an instance, the instance is launched into the appropriate default security group. A default security group includes a default rule that grants instances unrestricted network access to each other.

You can add or remove rules from your security groups using AuthorizeSecurityGroupIngress, AuthorizeSecurityGroupEgress, RevokeSecurityGroupIngress, and RevokeSecurityGroupEgress.

For more information about VPC security group limits, see Amazon VPC Limits .

CreateSnapshotCommand

Creates a snapshot of an EBS volume and stores it in Amazon S3. You can use snapshots for backups, to make copies of EBS volumes, and to save data before shutting down an instance.

The location of the source EBS volume determines where you can create the snapshot.

  • If the source volume is in a Region, you must create the snapshot in the same Region as the volume.

  • If the source volume is in a Local Zone, you can create the snapshot in the same Local Zone or in its parent Amazon Web Services Region.

  • If the source volume is on an Outpost, you can create the snapshot on the same Outpost or in its parent Amazon Web Services Region.

When a snapshot is created, any Amazon Web Services Marketplace product codes that are associated with the source volume are propagated to the snapshot.

You can take a snapshot of an attached volume that is in use. However, snapshots only capture data that has been written to your Amazon EBS volume at the time the snapshot command is issued; this might exclude any data that has been cached by any applications or the operating system. If you can pause any file systems on the volume long enough to take a snapshot, your snapshot should be complete. However, if you cannot pause all file writes to the volume, you should unmount the volume from within the instance, issue the snapshot command, and then remount the volume to ensure a consistent and complete snapshot. You may remount and use your volume while the snapshot status is pending.

When you create a snapshot for an EBS volume that serves as a root device, we recommend that you stop the instance before taking the snapshot.

Snapshots that are taken from encrypted volumes are automatically encrypted. Volumes that are created from encrypted snapshots are also automatically encrypted. Your encrypted volumes and any associated snapshots always remain protected. For more information, see Amazon EBS encryption  in the Amazon EBS User Guide.

CreateSnapshotsCommand

Creates crash-consistent snapshots of multiple EBS volumes attached to an Amazon EC2 instance. Volumes are chosen by specifying an instance. Each volume attached to the specified instance will produce one snapshot that is crash-consistent across the instance. You can include all of the volumes currently attached to the instance, or you can exclude the root volume or specific data (non-root) volumes from the multi-volume snapshot set.

The location of the source instance determines where you can create the snapshots.

  • If the source instance is in a Region, you must create the snapshots in the same Region as the instance.

  • If the source instance is in a Local Zone, you can create the snapshots in the same Local Zone or in its parent Amazon Web Services Region.

  • If the source instance is on an Outpost, you can create the snapshots on the same Outpost or in its parent Amazon Web Services Region.

CreateSpotDatafeedSubscriptionCommand

Creates a data feed for Spot Instances, enabling you to view Spot Instance usage logs. You can create one data feed per Amazon Web Services account. For more information, see Spot Instance data feed  in the Amazon EC2 User Guide.

CreateStoreImageTaskCommand

Stores an AMI as a single object in an Amazon S3 bucket.

To use this API, you must have the required permissions. For more information, see Permissions for storing and restoring AMIs using Amazon S3  in the Amazon EC2 User Guide.

For more information, see Store and restore an AMI using Amazon S3  in the Amazon EC2 User Guide.

CreateSubnetCidrReservationCommand

Creates a subnet CIDR reservation. For more information, see Subnet CIDR reservations  in the Amazon VPC User Guide and Manage prefixes for your network interfaces  in the Amazon EC2 User Guide.

CreateSubnetCommand

Creates a subnet in the specified VPC. For an IPv4 only subnet, specify an IPv4 CIDR block. If the VPC has an IPv6 CIDR block, you can create an IPv6 only subnet or a dual stack subnet instead. For an IPv6 only subnet, specify an IPv6 CIDR block. For a dual stack subnet, specify both an IPv4 CIDR block and an IPv6 CIDR block.

A subnet CIDR block must not overlap the CIDR block of an existing subnet in the VPC. After you create a subnet, you can't change its CIDR block.

The allowed size for an IPv4 subnet is between a /28 netmask (16 IP addresses) and a /16 netmask (65,536 IP addresses). Amazon Web Services reserves both the first four and the last IPv4 address in each subnet's CIDR block. They're not available for your use.

If you've associated an IPv6 CIDR block with your VPC, you can associate an IPv6 CIDR block with a subnet when you create it.

If you add more than one subnet to a VPC, they're set up in a star topology with a logical router in the middle.

When you stop an instance in a subnet, it retains its private IPv4 address. It's therefore possible to have a subnet with no running instances (they're all stopped), but no remaining IP addresses available.

For more information, see Subnets  in the Amazon VPC User Guide.

CreateTagsCommand

Adds or overwrites only the specified tags for the specified Amazon EC2 resource or resources. When you specify an existing tag key, the value is overwritten with the new value. Each resource can have a maximum of 50 tags. Each tag consists of a key and optional value. Tag keys must be unique per resource.

For more information about tags, see Tag your Amazon EC2 resources  in the Amazon Elastic Compute Cloud User Guide. For more information about creating IAM policies that control users' access to resources based on tags, see Supported resource-level permissions for Amazon EC2 API actions  in the Amazon Elastic Compute Cloud User Guide.

CreateTrafficMirrorFilterCommand

Creates a Traffic Mirror filter.

A Traffic Mirror filter is a set of rules that defines the traffic to mirror.

By default, no traffic is mirrored. To mirror traffic, use CreateTrafficMirrorFilterRule  to add Traffic Mirror rules to the filter. The rules you add define what traffic gets mirrored. You can also use ModifyTrafficMirrorFilterNetworkServices  to mirror supported network services.

CreateTrafficMirrorFilterRuleCommand

Creates a Traffic Mirror filter rule.

A Traffic Mirror rule defines the Traffic Mirror source traffic to mirror.

You need the Traffic Mirror filter ID when you create the rule.

CreateTrafficMirrorSessionCommand

Creates a Traffic Mirror session.

A Traffic Mirror session actively copies packets from a Traffic Mirror source to a Traffic Mirror target. Create a filter, and then assign it to the session to define a subset of the traffic to mirror, for example all TCP traffic.

The Traffic Mirror source and the Traffic Mirror target (monitoring appliances) can be in the same VPC, or in a different VPC connected via VPC peering or a transit gateway.

By default, no traffic is mirrored. Use CreateTrafficMirrorFilter  to create filter rules that specify the traffic to mirror.

CreateTrafficMirrorTargetCommand

Creates a target for your Traffic Mirror session.

A Traffic Mirror target is the destination for mirrored traffic. The Traffic Mirror source and the Traffic Mirror target (monitoring appliances) can be in the same VPC, or in different VPCs connected via VPC peering or a transit gateway.

A Traffic Mirror target can be a network interface, a Network Load Balancer, or a Gateway Load Balancer endpoint.

To use the target in a Traffic Mirror session, use CreateTrafficMirrorSession .

CreateTransitGatewayCommand

Creates a transit gateway.

You can use a transit gateway to interconnect your virtual private clouds (VPC) and on-premises networks. After the transit gateway enters the available state, you can attach your VPCs and VPN connections to the transit gateway.

To attach your VPCs, use CreateTransitGatewayVpcAttachment.

To attach a VPN connection, use CreateCustomerGateway to create a customer gateway and specify the ID of the customer gateway and the ID of the transit gateway in a call to CreateVpnConnection.

When you create a transit gateway, we create a default transit gateway route table and use it as the default association route table and the default propagation route table. You can use CreateTransitGatewayRouteTable to create additional transit gateway route tables. If you disable automatic route propagation, we do not create a default transit gateway route table. You can use EnableTransitGatewayRouteTablePropagation to propagate routes from a resource attachment to a transit gateway route table. If you disable automatic associations, you can use AssociateTransitGatewayRouteTable to associate a resource attachment with a transit gateway route table.

CreateTransitGatewayConnectCommand

Creates a Connect attachment from a specified transit gateway attachment. A Connect attachment is a GRE-based tunnel attachment that you can use to establish a connection between a transit gateway and an appliance.

A Connect attachment uses an existing VPC or Amazon Web Services Direct Connect attachment as the underlying transport mechanism.

CreateTransitGatewayConnectPeerCommand

Creates a Connect peer for a specified transit gateway Connect attachment between a transit gateway and an appliance.

The peer address and transit gateway address must be the same IP address family (IPv4 or IPv6).

For more information, see Connect peers  in the Amazon Web Services Transit Gateways Guide.

CreateTransitGatewayMulticastDomainCommand

Creates a multicast domain using the specified transit gateway.

The transit gateway must be in the available state before you create a domain. Use DescribeTransitGateways  to see the state of transit gateway.

CreateTransitGatewayPeeringAttachmentCommand

Requests a transit gateway peering attachment between the specified transit gateway (requester) and a peer transit gateway (accepter). The peer transit gateway can be in your account or a different Amazon Web Services account.

After you create the peering attachment, the owner of the accepter transit gateway must accept the attachment request.

CreateTransitGatewayPolicyTableCommand

Creates a transit gateway policy table.

CreateTransitGatewayPrefixListReferenceCommand

Creates a reference (route) to a prefix list in a specified transit gateway route table.

CreateTransitGatewayRouteCommand

Creates a static route for the specified transit gateway route table.

CreateTransitGatewayRouteTableAnnouncementCommand

Advertises a new transit gateway route table.

CreateTransitGatewayRouteTableCommand

Creates a route table for the specified transit gateway.

CreateTransitGatewayVpcAttachmentCommand

Attaches the specified VPC to the specified transit gateway.

If you attach a VPC with a CIDR range that overlaps the CIDR range of a VPC that is already attached, the new VPC CIDR range is not propagated to the default propagation route table.

To send VPC traffic to an attached transit gateway, add a route to the VPC route table using CreateRoute.

CreateVerifiedAccessEndpointCommand

An Amazon Web Services Verified Access endpoint is where you define your application along with an optional endpoint-level access policy.

CreateVerifiedAccessGroupCommand

An Amazon Web Services Verified Access group is a collection of Amazon Web Services Verified Access endpoints who's associated applications have similar security requirements. Each instance within a Verified Access group shares an Verified Access policy. For example, you can group all Verified Access instances associated with "sales" applications together and use one common Verified Access policy.

CreateVerifiedAccessInstanceCommand

An Amazon Web Services Verified Access instance is a regional entity that evaluates application requests and grants access only when your security requirements are met.

CreateVerifiedAccessTrustProviderCommand

A trust provider is a third-party entity that creates, maintains, and manages identity information for users and devices. When an application request is made, the identity information sent by the trust provider is evaluated by Verified Access before allowing or denying the application request.

CreateVolumeCommand

Creates an EBS volume that can be attached to an instance in the same Availability Zone.

You can create a new empty volume or restore a volume from an EBS snapshot. Any Amazon Web Services Marketplace product codes from the snapshot are propagated to the volume.

You can create encrypted volumes. Encrypted volumes must be attached to instances that support Amazon EBS encryption. Volumes that are created from encrypted snapshots are also automatically encrypted. For more information, see Amazon EBS encryption  in the Amazon EBS User Guide.

You can tag your volumes during creation. For more information, see Tag your Amazon EC2 resources  in the Amazon EC2 User Guide.

For more information, see Create an Amazon EBS volume  in the Amazon EBS User Guide.

CreateVpcBlockPublicAccessExclusionCommand

Create a VPC Block Public Access (BPA) exclusion. A VPC BPA exclusion is a mode that can be applied to a single VPC or subnet that exempts it from the account’s BPA mode and will allow bidirectional or egress-only access. You can create BPA exclusions for VPCs and subnets even when BPA is not enabled on the account to ensure that there is no traffic disruption to the exclusions when VPC BPA is turned on. To learn more about VPC BPA, see Block public access to VPCs and subnets  in the Amazon VPC User Guide.

CreateVpcCommand

Creates a VPC with the specified CIDR blocks. For more information, see IP addressing for your VPCs and subnets  in the Amazon VPC User Guide.

You can optionally request an IPv6 CIDR block for the VPC. You can request an Amazon-provided IPv6 CIDR block from Amazon's pool of IPv6 addresses or an IPv6 CIDR block from an IPv6 address pool that you provisioned through bring your own IP addresses (BYOIP ).

By default, each instance that you launch in the VPC has the default DHCP options, which include only a default DNS server that we provide (AmazonProvidedDNS). For more information, see DHCP option sets  in the Amazon VPC User Guide.

You can specify the instance tenancy value for the VPC when you create it. You can't change this value for the VPC after you create it. For more information, see Dedicated Instances  in the Amazon EC2 User Guide.

CreateVpcEndpointCommand

Creates a VPC endpoint. A VPC endpoint provides a private connection between the specified VPC and the specified endpoint service. You can use an endpoint service provided by Amazon Web Services, an Amazon Web Services Marketplace Partner, or another Amazon Web Services account. For more information, see the Amazon Web Services PrivateLink User Guide .

CreateVpcEndpointConnectionNotificationCommand

Creates a connection notification for a specified VPC endpoint or VPC endpoint service. A connection notification notifies you of specific endpoint events. You must create an SNS topic to receive notifications. For more information, see Creating an Amazon SNS topic  in the Amazon SNS Developer Guide.

You can create a connection notification for interface endpoints only.

CreateVpcEndpointServiceConfigurationCommand

Creates a VPC endpoint service to which service consumers (Amazon Web Services accounts, users, and IAM roles) can connect.

Before you create an endpoint service, you must create one of the following for your service:

If you set the private DNS name, you must prove that you own the private DNS domain name.

For more information, see the Amazon Web Services PrivateLink Guide .

CreateVpcPeeringConnectionCommand

Requests a VPC peering connection between two VPCs: a requester VPC that you own and an accepter VPC with which to create the connection. The accepter VPC can belong to another Amazon Web Services account and can be in a different Region to the requester VPC. The requester VPC and accepter VPC cannot have overlapping CIDR blocks.

Limitations and rules apply to a VPC peering connection. For more information, see the VPC peering limitations  in the VPC Peering Guide.

The owner of the accepter VPC must accept the peering request to activate the peering connection. The VPC peering connection request expires after 7 days, after which it cannot be accepted or rejected.

If you create a VPC peering connection request between VPCs with overlapping CIDR blocks, the VPC peering connection has a status of failed.

CreateVpnConnectionCommand

Creates a VPN connection between an existing virtual private gateway or transit gateway and a customer gateway. The supported connection type is ipsec.1.

The response includes information that you need to give to your network administrator to configure your customer gateway.

We strongly recommend that you use HTTPS when calling this operation because the response contains sensitive cryptographic information for configuring your customer gateway device.

If you decide to shut down your VPN connection for any reason and later create a new VPN connection, you must reconfigure your customer gateway with the new information returned from this call.

This is an idempotent operation. If you perform the operation more than once, Amazon EC2 doesn't return an error.

For more information, see Amazon Web Services Site-to-Site VPN  in the Amazon Web Services Site-to-Site VPN User Guide.

CreateVpnConnectionRouteCommand

Creates a static route associated with a VPN connection between an existing virtual private gateway and a VPN customer gateway. The static route allows traffic to be routed from the virtual private gateway to the VPN customer gateway.

For more information, see Amazon Web Services Site-to-Site VPN  in the Amazon Web Services Site-to-Site VPN User Guide.

CreateVpnGatewayCommand

Creates a virtual private gateway. A virtual private gateway is the endpoint on the VPC side of your VPN connection. You can create a virtual private gateway before creating the VPC itself.

For more information, see Amazon Web Services Site-to-Site VPN  in the Amazon Web Services Site-to-Site VPN User Guide.

DeleteCarrierGatewayCommand

Deletes a carrier gateway.

If you do not delete the route that contains the carrier gateway as the Target, the route is a blackhole route. For information about how to delete a route, see DeleteRoute .

DeleteClientVpnEndpointCommand

Deletes the specified Client VPN endpoint. You must disassociate all target networks before you can delete a Client VPN endpoint.

DeleteClientVpnRouteCommand

Deletes a route from a Client VPN endpoint. You can only delete routes that you manually added using the CreateClientVpnRoute action. You cannot delete routes that were automatically added when associating a subnet. To remove routes that have been automatically added, disassociate the target subnet from the Client VPN endpoint.

DeleteCoipCidrCommand

Deletes a range of customer-owned IP addresses.

DeleteCoipPoolCommand

Deletes a pool of customer-owned IP (CoIP) addresses.

DeleteCustomerGatewayCommand

Deletes the specified customer gateway. You must delete the VPN connection before you can delete the customer gateway.

DeleteDhcpOptionsCommand

DeleteEgressOnlyInternetGatewayCommand

Deletes an egress-only internet gateway.

DeleteFleetsCommand

Deletes the specified EC2 Fleets.

After you delete an EC2 Fleet, it launches no new instances.

You must also specify whether a deleted EC2 Fleet should terminate its instances. If you choose to terminate the instances, the EC2 Fleet enters the deleted_terminating state. Otherwise, the EC2 Fleet enters the deleted_running state, and the instances continue to run until they are interrupted or you terminate them manually.

For instant fleets, EC2 Fleet must terminate the instances when the fleet is deleted. Up to 1000 instances can be terminated in a single request to delete instant fleets. A deleted instant fleet with running instances is not supported.

Restrictions

  • You can delete up to 25 fleets of type instant in a single request.

  • You can delete up to 100 fleets of type maintain or request in a single request.

  • You can delete up to 125 fleets in a single request, provided you do not exceed the quota for each fleet type, as specified above.

  • If you exceed the specified number of fleets to delete, no fleets are deleted.

When you delete an interface endpoint, we delete its endpoint network interfaces.

DeleteVpcPeeringConnectionCommand

Deletes a VPC peering connection. Either the owner of the requester VPC or the owner of the accepter VPC can delete the VPC peering connection if it's in the active state. The owner of the requester VPC can delete a VPC peering connection in the pending-acceptance state. You cannot delete a VPC peering connection that's in the failed or rejected state.

DeleteVpnConnectionCommand

Deletes the specified VPN connection.

If you're deleting the VPC and its associated components, we recommend that you detach the virtual private gateway from the VPC and delete the VPC before deleting the VPN connection. If you believe that the tunnel credentials for your VPN connection have been compromised, you can delete the VPN connection and create a new one that has new keys, without needing to delete the VPC or virtual private gateway. If you create a new VPN connection, you must reconfigure the customer gateway device using the new configuration information returned with the new VPN connection ID.

For certificate-based authentication, delete all Certificate Manager (ACM) private certificates used for the Amazon Web Services-side tunnel endpoints for the VPN connection before deleting the VPN connection.

DeleteVpnConnectionRouteCommand

Deletes the specified static route associated with a VPN connection between an existing virtual private gateway and a VPN customer gateway. The static route allows traffic to be routed from the virtual private gateway to the VPN customer gateway.

DeleteVpnGatewayCommand

The images available to you include public images, private images that you own, and private images owned by other Amazon Web Services accounts for which you have explicit launch permissions.

Recently deregistered images appear in the returned results for a short interval and then return empty results. After all instances that reference a deregistered AMI are terminated, specifying the ID of the image will eventually return an error indicating that the AMI ID cannot be found.

When Allowed AMIs is set to enabled, only allowed images are returned in the results, with the imageAllowed field set to true for each image. In audit-mode, the imageAllowed field is set to true for images that meet the account's Allowed AMIs criteria, and false for images that don't meet the criteria. For more information, see EnableAllowedImagesSettings.

We strongly recommend using only paginated requests. Unpaginated requests are susceptible to throttling and timeouts.

DescribeInstanceCreditSpecificationsCommand

Describes the credit option for CPU usage of the specified burstable performance instances. The credit options are standard and unlimited.

If you do not specify an instance ID, Amazon EC2 returns burstable performance instances with the unlimited credit option, as well as instances that were previously configured as T2, T3, and T3a with the unlimited credit option. For example, if you resize a T2 instance, while it is configured as unlimited, to an M4 instance, Amazon EC2 returns the M4 instance.

If you specify one or more instance IDs, Amazon EC2 returns the credit option (standard or unlimited) of those instances. If you specify an instance ID that is not valid, such as an instance that is not a burstable performance instance, an error is returned.

Recently terminated instances might appear in the returned results. This interval is usually less than one hour.

If an Availability Zone is experiencing a service disruption and you specify instance IDs in the affected zone, or do not specify any instance IDs at all, the call fails. If you specify only instance IDs in an unaffected zone, the call works normally.

If you do not specify event windows IDs or filters, the output includes information for all event windows, which can affect performance. We recommend that you use pagination to ensure that the operation returns quickly and successfully.

For more information, see Define event windows for scheduled events  in the Amazon EC2 User Guide.

DescribeInstanceImageMetadataCommand

Describes the AMI that was used to launch an instance, even if the AMI is deprecated, deregistered, made private (no longer public or shared with your account), or not allowed.

If you specify instance IDs, the output includes information for only the specified instances. If you specify filters, the output includes information for only those instances that meet the filter criteria. If you do not specify instance IDs or filters, the output includes information for all instances, which can affect performance.

If you specify an instance ID that is not valid, an instance that doesn't exist, or an instance that you do not own, an error (InvalidInstanceID.NotFound) is returned.

Recently terminated instances might appear in the returned results. This interval is usually less than one hour.

In the rare case where an Availability Zone is experiencing a service disruption and you specify instance IDs that are in the affected Availability Zone, or do not specify any instance IDs at all, the call fails. If you specify only instance IDs that are in an unaffected Availability Zone, the call works normally.

The order of the elements in the response, including those within nested structures, might vary. Applications should not assume the elements appear in a particular order.

DescribeInstanceStatusCommand

Describes the status of the specified instances or all of your instances. By default, only running instances are described, unless you specifically indicate to return the status of all instances.

Instance status includes the following components:

  • Status checks - Amazon EC2 performs status checks on running EC2 instances to identify hardware and software issues. For more information, see Status checks for your instances  and Troubleshoot instances with failed status checks  in the Amazon EC2 User Guide.

  • Scheduled events - Amazon EC2 can schedule events (such as reboot, stop, or terminate) for your instances related to hardware issues, software updates, or system maintenance. For more information, see Scheduled events for your instances  in the Amazon EC2 User Guide.

  • Instance state - You can manage your instances from the moment you launch them through their termination. For more information, see Instance lifecycle  in the Amazon EC2 User Guide.

The order of the elements in the response, including those within nested structures, might vary. Applications should not assume the elements appear in a particular order.

The order of the elements in the response, including those within nested structures, might vary. Applications should not assume the elements appear in a particular order.

DescribeReservedInstancesListingsCommand

Describes your account's Reserved Instance listings in the Reserved Instance Marketplace.

The Reserved Instance Marketplace matches sellers who want to resell Reserved Instance capacity that they no longer need with buyers who want to purchase additional capacity. Reserved Instances bought and sold through the Reserved Instance Marketplace work like any other Reserved Instances.

As a seller, you choose to list some or all of your Reserved Instances, and you specify the upfront price to receive for them. Your Reserved Instances are then listed in the Reserved Instance Marketplace and are available for purchase.

As a buyer, you specify the configuration of the Reserved Instance to purchase, and the Marketplace matches what you're searching for with what's available. The Marketplace first sells the lowest priced Reserved Instances to you, and continues to sell available Reserved Instance listings to you until your demand is met. You are charged based on the total price of all of the listings that you purchase.

For more information, see Sell in the Reserved Instance Marketplace  in the Amazon EC2 User Guide.

The order of the elements in the response, including those within nested structures, might vary. Applications should not assume the elements appear in a particular order.

DescribeReservedInstancesModificationsCommand

Describes the modifications made to your Reserved Instances. If no parameter is specified, information about all your Reserved Instances modification requests is returned. If a modification ID is specified, only information about the specific modification is returned.

For more information, see Modify Reserved Instances  in the Amazon EC2 User Guide.

The order of the elements in the response, including those within nested structures, might vary. Applications should not assume the elements appear in a particular order.

DescribeReservedInstancesOfferingsCommand

Describes Reserved Instance offerings that are available for purchase. With Reserved Instances, you purchase the right to launch instances for a period of time. During that time period, you do not receive insufficient capacity errors, and you pay a lower usage rate than the rate charged for On-Demand instances for the actual time used.

If you have listed your own Reserved Instances for sale in the Reserved Instance Marketplace, they will be excluded from these results. This is to ensure that you do not purchase your own Reserved Instances.

For more information, see Sell in the Reserved Instance Marketplace  in the Amazon EC2 User Guide.

The order of the elements in the response, including those within nested structures, might vary. Applications should not assume the elements appear in a particular order.

DescribeRouteTablesCommand

Describes your route tables. The default is to describe all your route tables. Alternatively, you can specify specific route table IDs or filter the results to include only the route tables that match specific criteria.

Each subnet in your VPC must be associated with a route table. If a subnet is not explicitly associated with any route table, it is implicitly associated with the main route table. This command does not return the subnet ID for implicit associations.

For more information, see Route tables  in the Amazon VPC User Guide.

DescribeScheduledInstanceAvailabilityCommand

Finds available schedules that meet the specified criteria.

You can search for an available schedule no more than 3 months in advance. You must meet the minimum required duration of 1,200 hours per year. For example, the minimum daily schedule is 4 hours, the minimum weekly schedule is 24 hours, and the minimum monthly schedule is 100 hours.

After you find a schedule that meets your needs, call PurchaseScheduledInstances to purchase Scheduled Instances with that schedule.

For more information about EBS snapshots, see Amazon EBS snapshots  in the Amazon EBS User Guide.

DescribeSnapshotTierStatusCommand

Describes the storage tier status of one or more Amazon EBS snapshots.

DescribeSnapshotsCommand

Describes the specified EBS snapshots available to you or all of the EBS snapshots available to you.

The snapshots available to you include public snapshots, private snapshots that you own, and private snapshots owned by other Amazon Web Services accounts for which you have explicit create volume permissions.

The create volume permissions fall into the following categories:

  • public: The owner of the snapshot granted create volume permissions for the snapshot to the all group. All Amazon Web Services accounts have create volume permissions for these snapshots.

  • explicit: The owner of the snapshot granted create volume permissions to a specific Amazon Web Services account.

  • implicit: An Amazon Web Services account has implicit create volume permissions for all snapshots it owns.

The list of snapshots returned can be filtered by specifying snapshot IDs, snapshot owners, or Amazon Web Services accounts with create volume permissions. If no options are specified, Amazon EC2 returns all snapshots for which you have create volume permissions.

If you specify one or more snapshot IDs, only snapshots that have the specified IDs are returned. If you specify an invalid snapshot ID, an error is returned. If you specify a snapshot ID for which you do not have access, it is not included in the returned results.

If you specify one or more snapshot owners using the OwnerIds option, only snapshots from the specified owners and for which you have access are returned. The results can include the Amazon Web Services account IDs of the specified owners, amazon for snapshots owned by Amazon, or self for snapshots that you own.

If you specify a list of restorable users, only snapshots with create snapshot permissions for those users are returned. You can specify Amazon Web Services account IDs (if you own the snapshots), self for snapshots for which you own or have explicit permissions, or all for public snapshots.

If you are describing a long list of snapshots, we recommend that you paginate the output to make the list more manageable. For more information, see Pagination .

To get the state of fast snapshot restores for a snapshot, use DescribeFastSnapshotRestores.

For more information about EBS snapshots, see Amazon EBS snapshots  in the Amazon EBS User Guide.

We strongly recommend using only paginated requests. Unpaginated requests are susceptible to throttling and timeouts.

DescribeSpotDatafeedSubscriptionCommand

Describes the data feed for Spot Instances. For more information, see Spot Instance data feed  in the Amazon EC2 User Guide.

DescribeSpotFleetInstancesCommand

Describes the running instances for the specified Spot Fleet.

DescribeSpotFleetRequestHistoryCommand

Describes the events for the specified Spot Fleet request during the specified time.

Spot Fleet events are delayed by up to 30 seconds before they can be described. This ensures that you can query by the last evaluated time and not miss a recorded event. Spot Fleet events are available for 48 hours.

For more information, see Monitor fleet events using Amazon EventBridge  in the Amazon EC2 User Guide.

DescribeSpotFleetRequestsCommand

Describes your Spot Fleet requests.

Spot Fleet requests are deleted 48 hours after they are canceled and their instances are terminated.

DescribeSpotInstanceRequestsCommand

Describes the specified Spot Instance requests.

You can use DescribeSpotInstanceRequests to find a running Spot Instance by examining the response. If the status of the Spot Instance is fulfilled, the instance ID appears in the response and contains the identifier of the instance. Alternatively, you can use DescribeInstances  with a filter to look for instances where the instance lifecycle is spot.

We recommend that you set MaxResults to a value between 5 and 1000 to limit the number of items returned. This paginates the output, which makes the list more manageable and returns the items faster. If the list of items exceeds your MaxResults value, then that number of items is returned along with a NextToken value that can be passed to a subsequent DescribeSpotInstanceRequests request to retrieve the remaining items.

Spot Instance requests are deleted four hours after they are canceled and their instances are terminated.

DescribeSpotPriceHistoryCommand

Describes the Spot price history. For more information, see Spot Instance pricing history  in the Amazon EC2 User Guide.

When you specify a start and end time, the operation returns the prices of the instance types within that time range. It also returns the last price change before the start time, which is the effective price as of the start time.

DescribeStaleSecurityGroupsCommand

Describes the stale security group rules for security groups referenced across a VPC peering connection, transit gateway connection, or with a security group VPC association. Rules are stale when they reference a deleted security group. Rules can also be stale if they reference a security group in a peer VPC for which the VPC peering connection has been deleted, across a transit gateway where the transit gateway has been deleted (or the transit gateway security group referencing feature  has been disabled), or if a security group VPC association has been disassociated.

DescribeStoreImageTasksCommand

Describes the progress of the AMI store tasks. You can describe the store tasks for specified AMIs. If you don't specify the AMIs, you get a paginated list of store tasks from the last 31 days.

For each AMI task, the response indicates if the task is InProgress, Completed, or Failed. For tasks InProgress, the response shows the estimated progress as a percentage.

Tasks are listed in reverse chronological order. Currently, only tasks from the past 31 days can be viewed.

To use this API, you must have the required permissions. For more information, see Permissions for storing and restoring AMIs using Amazon S3  in the Amazon EC2 User Guide.

For more information, see Store and restore an AMI using Amazon S3  in the Amazon EC2 User Guide.

DescribeVerifiedAccessGroupsCommand

Describes the specified Verified Access groups.

DescribeVerifiedAccessInstanceLoggingConfigurationsCommand

Describes the specified Amazon Web Services Verified Access instances.

DescribeVerifiedAccessInstancesCommand

Describes the specified Amazon Web Services Verified Access instances.

DescribeVerifiedAccessTrustProvidersCommand

Describes the specified Amazon Web Services Verified Access trust providers.

DescribeVolumeAttributeCommand

Describes the specified attribute of the specified volume. You can specify only one attribute at a time.

For more information about EBS volumes, see Amazon EBS volumes  in the Amazon EBS User Guide.

DescribeVolumeStatusCommand

Describes the status of the specified volumes. Volume status provides the result of the checks performed on your volumes to determine events that can impair the performance of your volumes. The performance of a volume can be affected if an issue occurs on the volume's underlying host. If the volume's underlying host experiences a power outage or system issue, after the system is restored, there could be data inconsistencies on the volume. Volume events notify you if this occurs. Volume actions notify you if any action needs to be taken in response to the event.

The DescribeVolumeStatus operation provides the following information about the specified volumes:

Status: Reflects the current status of the volume. The possible values are ok, impaired , warning, or insufficient-data. If all checks pass, the overall status of the volume is ok. If the check fails, the overall status is impaired. If the status is insufficient-data, then the checks might still be taking place on your volume at the time. We recommend that you retry the request. For more information about volume status, see Monitor the status of your volumes  in the Amazon EBS User Guide.

Events: Reflect the cause of a volume status and might require you to take action. For example, if your volume returns an impaired status, then the volume event might be potential-data-inconsistency. This means that your volume has been affected by an issue with the underlying host, has all I/O operations disabled, and might have inconsistent data.

Actions: Reflect the actions you might have to take in response to an event. For example, if the status of the volume is impaired and the volume event shows potential-data-inconsistency, then the action shows enable-volume-io. This means that you may want to enable the I/O operations for the volume by calling the EnableVolumeIO action and then check the volume for data consistency.

Volume status is based on the volume status checks, and does not reflect the volume state. Therefore, volume status does not indicate volumes in the error state (for example, when a volume is incapable of accepting I/O.)

The order of the elements in the response, including those within nested structures, might vary. Applications should not assume the elements appear in a particular order.

DescribeVolumesCommand

Describes the specified EBS volumes or all of your EBS volumes.

If you are describing a long list of volumes, we recommend that you paginate the output to make the list more manageable. For more information, see Pagination .

For more information about EBS volumes, see Amazon EBS volumes  in the Amazon EBS User Guide.

We strongly recommend using only paginated requests. Unpaginated requests are susceptible to throttling and timeouts.

The order of the elements in the response, including those within nested structures, might vary. Applications should not assume the elements appear in a particular order.

DescribeVolumesModificationsCommand

Describes the most recent volume modification request for the specified EBS volumes.

For more information, see Monitor the progress of volume modifications  in the Amazon EBS User Guide.

DescribeVpcAttributeCommand

Describes the specified attribute of the specified VPC. You can specify only one attribute at a time.

DescribeVpcBlockPublicAccessExclusionsCommand

Describe VPC Block Public Access (BPA) exclusions. A VPC BPA exclusion is a mode that can be applied to a single VPC or subnet that exempts it from the account’s BPA mode and will allow bidirectional or egress-only access. You can create BPA exclusions for VPCs and subnets even when BPA is not enabled on the account to ensure that there is no traffic disruption to the exclusions when VPC BPA is turned on. To learn more about VPC BPA, see Block public access to VPCs and subnets  in the Amazon VPC User Guide.

DescribeVpcBlockPublicAccessOptionsCommand

Describe VPC Block Public Access (BPA) options. VPC Block Public Access (BPA) enables you to block resources in VPCs and subnets that you own in a Region from reaching or being reached from the internet through internet gateways and egress-only internet gateways. To learn more about VPC BPA, see Block public access to VPCs and subnets  in the Amazon VPC User Guide.

DescribeVpcClassicLinkCommand

This action is deprecated.

Describes the ClassicLink status of the specified VPCs.

DescribeVpcClassicLinkDnsSupportCommand

This action is deprecated.

Describes the ClassicLink DNS support status of one or more VPCs. If enabled, the DNS hostname of a linked EC2-Classic instance resolves to its private IP address when addressed from an instance in the VPC to which it's linked. Similarly, the DNS hostname of an instance in a VPC resolves to its private IP address when addressed from a linked EC2-Classic instance.

DescribeVpcEndpointAssociationsCommand

Describes the VPC resources, VPC endpoint services, Amazon Lattice services, or service networks associated with the VPC endpoint.

DescribeVpcEndpointConnectionNotificationsCommand

For more information, see Amazon Web Services Site-to-Site VPN  in the Amazon Web Services Site-to-Site VPN User Guide.

DetachClassicLinkVpcCommand

This action is deprecated.

Unlinks (detaches) a linked EC2-Classic instance from a VPC. After the instance has been unlinked, the VPC security groups are no longer associated with it. An instance is automatically unlinked from a VPC when it's stopped.

DetachInternetGatewayCommand

Detaches an internet gateway from a VPC, disabling connectivity between the internet and the VPC. The VPC must not contain any running instances with Elastic IP addresses or public IPv4 addresses.

DetachNetworkInterfaceCommand

Detaches a network interface from an instance.

DetachVerifiedAccessTrustProviderCommand

Detaches the specified Amazon Web Services Verified Access trust provider from the specified Amazon Web Services Verified Access instance.

DetachVolumeCommand

Detaches an EBS volume from an instance. Make sure to unmount any file systems on the device within your operating system before detaching the volume. Failure to do so can result in the volume becoming stuck in the busy state while detaching. If this happens, detachment can be delayed indefinitely until you unmount the volume, force detachment, reboot the instance, or all three. If an EBS volume is the root device of an instance, it can't be detached while the instance is running. To detach the root volume, stop the instance first.

When a volume with an Amazon Web Services Marketplace product code is detached from an instance, the product code is no longer associated with the instance.

You can't detach or force detach volumes that are attached to Amazon ECS or Fargate tasks. Attempting to do this results in the UnsupportedOperationException exception with the Unable to detach volume attached to ECS tasks error message.

For more information, see Detach an Amazon EBS volume  in the Amazon EBS User Guide.

DetachVpnGatewayCommand

Detaches a virtual private gateway from a VPC. You do this if you're planning to turn off the VPC and not use it anymore. You can confirm a virtual private gateway has been completely detached from a VPC by describing the virtual private gateway (any attachments to the virtual private gateway are also described).

You must wait for the attachment's state to switch to detached before you can delete the VPC or attach a different VPC to the virtual private gateway.

DisableAddressTransferCommand

Disables Elastic IP address transfer. For more information, see Transfer Elastic IP addresses  in the Amazon VPC User Guide.

DisableAllowedImagesSettingsCommand

Disables Allowed AMIs for your account in the specified Amazon Web Services Region. When set to disabled, the image criteria in your Allowed AMIs settings do not apply, and no restrictions are placed on AMI discoverability or usage. Users in your account can launch instances using any public AMI or AMI shared with your account.

The Allowed AMIs feature does not restrict the AMIs owned by your account. Regardless of the criteria you set, the AMIs created by your account will always be discoverable and usable by users in your account.

For more information, see Control the discovery and use of AMIs in Amazon EC2 with Allowed AMIs  in Amazon EC2 User Guide.

DisableAwsNetworkPerformanceMetricSubscriptionCommand

Disables Infrastructure Performance metric subscriptions.

DisableEbsEncryptionByDefaultCommand

Disables EBS encryption by default for your account in the current Region.

After you disable encryption by default, you can still create encrypted volumes by enabling encryption when you create each volume.

Disabling encryption by default does not change the encryption status of your existing volumes.

For more information, see Amazon EBS encryption  in the Amazon EBS User Guide.

DisableFastLaunchCommand

Discontinue Windows fast launch for a Windows AMI, and clean up existing pre-provisioned snapshots. After you disable Windows fast launch, the AMI uses the standard launch process for each new instance. Amazon EC2 must remove all pre-provisioned snapshots before you can enable Windows fast launch again.

You can only change these settings for Windows AMIs that you own or that have been shared with you.

DisableFastSnapshotRestoresCommand

Disables fast snapshot restores for the specified snapshots in the specified Availability Zones.

DisableImageBlockPublicAccessCommand

Disables block public access for AMIs at the account level in the specified Amazon Web Services Region. This removes the block public access restriction from your account. With the restriction removed, you can publicly share your AMIs in the specified Amazon Web Services Region.

The API can take up to 10 minutes to configure this setting. During this time, if you run GetImageBlockPublicAccessState , the response will be block-new-sharing. When the API has completed the configuration, the response will be unblocked.

For more information, see Block public access to your AMIs  in the Amazon EC2 User Guide.

DisableImageCommand

Sets the AMI state to disabled and removes all launch permissions from the AMI. A disabled AMI can't be used for instance launches.

A disabled AMI can't be shared. If an AMI was public or previously shared, it is made private. If an AMI was shared with an Amazon Web Services account, organization, or Organizational Unit, they lose access to the disabled AMI.

A disabled AMI does not appear in DescribeImages  API calls by default.

Only the AMI owner can disable an AMI.

You can re-enable a disabled AMI using EnableImage .

For more information, see Disable an AMI  in the Amazon EC2 User Guide.

DisableImageDeprecationCommand

Cancels the deprecation of the specified AMI.

For more information, see Deprecate an AMI  in the Amazon EC2 User Guide.

DisableImageDeregistrationProtectionCommand

Disables deregistration protection for an AMI. When deregistration protection is disabled, the AMI can be deregistered.

If you chose to include a 24-hour cooldown period when you enabled deregistration protection for the AMI, then, when you disable deregistration protection, you won’t immediately be able to deregister the AMI.

For more information, see Protect an AMI from deregistration  in the Amazon EC2 User Guide.

DisableIpamOrganizationAdminAccountCommand

Disable the IPAM account. For more information, see Enable integration with Organizations  in the Amazon VPC IPAM User Guide.

DisableSerialConsoleAccessCommand

Disables access to the EC2 serial console of all instances for your account. By default, access to the EC2 serial console is disabled for your account. For more information, see Manage account access to the EC2 serial console  in the Amazon EC2 User Guide.

DisableSnapshotBlockPublicAccessCommand

Disables the block public access for snapshots setting at the account level for the specified Amazon Web Services Region. After you disable block public access for snapshots in a Region, users can publicly share snapshots in that Region.

Enabling block public access for snapshots in block-all-sharing mode does not change the permissions for snapshots that are already publicly shared. Instead, it prevents these snapshots from be publicly visible and publicly accessible. Therefore, the attributes for these snapshots still indicate that they are publicly shared, even though they are not publicly available.

If you disable block public access , these snapshots will become publicly available again.

For more information, see Block public access for snapshots  in the Amazon EBS User Guide .

DisableTransitGatewayRouteTablePropagationCommand

Disables the specified resource attachment from propagating routes to the specified propagation route table.

DisableVgwRoutePropagationCommand

Disables a virtual private gateway (VGW) from propagating routes to a specified route table of a VPC.

DisableVpcClassicLinkCommand

This action is deprecated.

Disables ClassicLink for a VPC. You cannot disable ClassicLink for a VPC that has EC2-Classic instances linked to it.

DisableVpcClassicLinkDnsSupportCommand

This action is deprecated.

Disables ClassicLink DNS support for a VPC. If disabled, DNS hostnames resolve to public IP addresses when addressed between a linked EC2-Classic instance and instances in the VPC to which it's linked.

You must specify a VPC ID in the request.

DisassociateAddressCommand

Disassociates an Elastic IP address from the instance or network interface it's associated with.

This is an idempotent operation. If you perform the operation more than once, Amazon EC2 doesn't return an error.

DisassociateCapacityReservationBillingOwnerCommand

Cancels a pending request to assign billing of the unused capacity of a Capacity Reservation to a consumer account, or revokes a request that has already been accepted. For more information, see Billing assignment for shared Amazon EC2 Capacity Reservations .

DisassociateClientVpnTargetNetworkCommand

Disassociates a target network from the specified Client VPN endpoint. When you disassociate the last target network from a Client VPN, the following happens:

  • The route that was automatically added for the VPC is deleted

  • All active client connections are terminated

  • New client connections are disallowed

  • The Client VPN endpoint's status changes to pending-associate

DisassociateEnclaveCertificateIamRoleCommand

Disassociates an IAM role from an Certificate Manager (ACM) certificate. Disassociating an IAM role from an ACM certificate removes the Amazon S3 object that contains the certificate, certificate chain, and encrypted private key from the Amazon S3 bucket. It also revokes the IAM role's permission to use the KMS key used to encrypt the private key. This effectively revokes the role's permission to use the certificate.

DisassociateIamInstanceProfileCommand

Disassociates an IAM instance profile from a running or stopped instance.

Use DescribeIamInstanceProfileAssociations to get the association ID.

DisassociateInstanceEventWindowCommand

Disassociates one or more targets from an event window.

For more information, see Define event windows for scheduled events  in the Amazon EC2 User Guide.

DisassociateIpamByoasnCommand

Remove the association between your Autonomous System Number (ASN) and your BYOIP CIDR. You may want to use this action to disassociate an ASN from a CIDR or if you want to swap ASNs. For more information, see Tutorial: Bring your ASN to IPAM  in the Amazon VPC IPAM guide.

DisassociateIpamResourceDiscoveryCommand

Disassociates a resource discovery from an Amazon VPC IPAM. A resource discovery is an IPAM component that enables IPAM to manage and monitor resources that belong to the owning account.

DisassociateNatGatewayAddressCommand

Disassociates secondary Elastic IP addresses (EIPs) from a public NAT gateway. You cannot disassociate your primary EIP. For more information, see Edit secondary IP address associations  in the Amazon VPC User Guide.

While disassociating is in progress, you cannot associate/disassociate additional EIPs while the connections are being drained. You are, however, allowed to delete the NAT gateway.

An EIP is released only at the end of MaxDrainDurationSeconds. It stays associated and supports the existing connections but does not support any new connections (new connections are distributed across the remaining associated EIPs). As the existing connections drain out, the EIPs (and the corresponding private IP addresses mapped to them) are released.

DisassociateRouteTableCommand

Disassociates a subnet or gateway from a route table.

After you perform this action, the subnet no longer uses the routes in the route table. Instead, it uses the routes in the VPC's main route table. For more information about route tables, see Route tables  in the Amazon VPC User Guide.

DisassociateSecurityGroupVpcCommand

Disassociates a security group from a VPC. You cannot disassociate the security group if any Elastic network interfaces in the associated VPC are still associated with the security group.Note that the disassociation is asynchronous and you can check the status of the request with DescribeSecurityGroupVpcAssociations .

DisassociateSubnetCidrBlockCommand

Disassociates a CIDR block from a subnet. Currently, you can disassociate an IPv6 CIDR block only. You must detach or delete all gateways and resources that are associated with the CIDR block before you can disassociate it.

DisassociateTransitGatewayMulticastDomainCommand

Disassociates the specified subnets from the transit gateway multicast domain.

DisassociateTransitGatewayPolicyTableCommand

Removes the association between an an attachment and a policy table.

DisassociateTransitGatewayRouteTableCommand

Disassociates a resource attachment from a transit gateway route table.

DisassociateTrunkInterfaceCommand

Removes an association between a branch network interface with a trunk network interface.

DisassociateVpcCidrBlockCommand

Disassociates a CIDR block from a VPC. To disassociate the CIDR block, you must specify its association ID. You can get the association ID by using DescribeVpcs. You must detach or delete all gateways and resources that are associated with the CIDR block before you can disassociate it.

You cannot disassociate the CIDR block with which you originally created the VPC (the primary CIDR block).

EnableAddressTransferCommand

Enables Elastic IP address transfer. For more information, see Transfer Elastic IP addresses  in the Amazon VPC User Guide.

EnableAllowedImagesSettingsCommand

Enables Allowed AMIs for your account in the specified Amazon Web Services Region. Two values are accepted:

  • enabled: The image criteria in your Allowed AMIs settings are applied. As a result, only AMIs matching these criteria are discoverable and can be used by your account to launch instances.

  • audit-mode: The image criteria in your Allowed AMIs settings are not applied. No restrictions are placed on AMI discoverability or usage. Users in your account can launch instances using any public AMI or AMI shared with your account.

    The purpose of audit-mode is to indicate which AMIs will be affected when Allowed AMIs is enabled. In audit-mode, each AMI displays either "ImageAllowed": true or "ImageAllowed": false to indicate whether the AMI will be discoverable and available to users in the account when Allowed AMIs is enabled.

The Allowed AMIs feature does not restrict the AMIs owned by your account. Regardless of the criteria you set, the AMIs created by your account will always be discoverable and usable by users in your account.

For more information, see Control the discovery and use of AMIs in Amazon EC2 with Allowed AMIs  in Amazon EC2 User Guide.

EnableAwsNetworkPerformanceMetricSubscriptionCommand

Enables Infrastructure Performance subscriptions.

EnableEbsEncryptionByDefaultCommand

Enables EBS encryption by default for your account in the current Region.

After you enable encryption by default, the EBS volumes that you create are always encrypted, either using the default KMS key or the KMS key that you specified when you created each volume. For more information, see Amazon EBS encryption  in the Amazon EBS User Guide.

You can specify the default KMS key for encryption by default using ModifyEbsDefaultKmsKeyId or ResetEbsDefaultKmsKeyId.

Enabling encryption by default has no effect on the encryption status of your existing volumes.

After you enable encryption by default, you can no longer launch instances using instance types that do not support encryption. For more information, see Supported instance types .

EnableFastLaunchCommand

When you enable Windows fast launch for a Windows AMI, images are pre-provisioned, using snapshots to launch instances up to 65% faster. To create the optimized Windows image, Amazon EC2 launches an instance and runs through Sysprep steps, rebooting as required. Then it creates a set of reserved snapshots that are used for subsequent launches. The reserved snapshots are automatically replenished as they are used, depending on your settings for launch frequency.

You can only change these settings for Windows AMIs that you own or that have been shared with you.

EnableFastSnapshotRestoresCommand

Enables fast snapshot restores for the specified snapshots in the specified Availability Zones.

You get the full benefit of fast snapshot restores after they enter the enabled state. To get the current state of fast snapshot restores, use DescribeFastSnapshotRestores. To disable fast snapshot restores, use DisableFastSnapshotRestores.

For more information, see Amazon EBS fast snapshot restore  in the Amazon EBS User Guide.

EnableImageBlockPublicAccessCommand

Enables block public access for AMIs at the account level in the specified Amazon Web Services Region. This prevents the public sharing of your AMIs. However, if you already have public AMIs, they will remain publicly available.

The API can take up to 10 minutes to configure this setting. During this time, if you run GetImageBlockPublicAccessState , the response will be unblocked. When the API has completed the configuration, the response will be block-new-sharing.

For more information, see Block public access to your AMIs  in the Amazon EC2 User Guide.

EnableImageCommand

Re-enables a disabled AMI. The re-enabled AMI is marked as available and can be used for instance launches, appears in describe operations, and can be shared. Amazon Web Services accounts, organizations, and Organizational Units that lost access to the AMI when it was disabled do not regain access automatically. Once the AMI is available, it can be shared with them again.

Only the AMI owner can re-enable a disabled AMI.

For more information, see Disable an AMI  in the Amazon EC2 User Guide.

EnableImageDeprecationCommand

Enables deprecation of the specified AMI at the specified date and time.

For more information, see Deprecate an AMI  in the Amazon EC2 User Guide.

EnableImageDeregistrationProtectionCommand

Enables deregistration protection for an AMI. When deregistration protection is enabled, the AMI can't be deregistered.

To allow the AMI to be deregistered, you must first disable deregistration protection using DisableImageDeregistrationProtection.

For more information, see Protect an AMI from deregistration  in the Amazon EC2 User Guide.

EnableIpamOrganizationAdminAccountCommand

Enable an Organizations member account as the IPAM admin account. You cannot select the Organizations management account as the IPAM admin account. For more information, see Enable integration with Organizations  in the Amazon VPC IPAM User Guide.

EnableReachabilityAnalyzerOrganizationSharingCommand

Establishes a trust relationship between Reachability Analyzer and Organizations. This operation must be performed by the management account for the organization.

After you establish a trust relationship, a user in the management account or a delegated administrator account can run a cross-account analysis using resources from the member accounts.

EnableSerialConsoleAccessCommand

Enables access to the EC2 serial console of all instances for your account. By default, access to the EC2 serial console is disabled for your account. For more information, see Manage account access to the EC2 serial console  in the Amazon EC2 User Guide.

EnableSnapshotBlockPublicAccessCommand

Enables or modifies the block public access for snapshots setting at the account level for the specified Amazon Web Services Region. After you enable block public access for snapshots in a Region, users can no longer request public sharing for snapshots in that Region. Snapshots that are already publicly shared are either treated as private or they remain publicly shared, depending on the State that you specify.

Enabling block public access for snapshots in block all sharing mode does not change the permissions for snapshots that are already publicly shared. Instead, it prevents these snapshots from be publicly visible and publicly accessible. Therefore, the attributes for these snapshots still indicate that they are publicly shared, even though they are not publicly available.

If you later disable block public access or change the mode to block new sharing, these snapshots will become publicly available again.

For more information, see Block public access for snapshots  in the Amazon EBS User Guide.

EnableTransitGatewayRouteTablePropagationCommand

Enables the specified attachment to propagate routes to the specified propagation route table.

EnableVgwRoutePropagationCommand

Enables a virtual private gateway (VGW) to propagate routes to the specified route table of a VPC.

EnableVpcClassicLinkCommand

This action is deprecated.

Enables a VPC for ClassicLink. You can then link EC2-Classic instances to your ClassicLink-enabled VPC to allow communication over private IP addresses. You cannot enable your VPC for ClassicLink if any of your VPC route tables have existing routes for address ranges within the 10.0.0.0/8 IP address range, excluding local routes for VPCs in the 10.0.0.0/16 and 10.1.0.0/16 IP address ranges.

EnableVpcClassicLinkDnsSupportCommand

This action is deprecated.

Enables a VPC to support DNS hostname resolution for ClassicLink. If enabled, the DNS hostname of a linked EC2-Classic instance resolves to its private IP address when addressed from an instance in the VPC to which it's linked. Similarly, the DNS hostname of an instance in a VPC resolves to its private IP address when addressed from a linked EC2-Classic instance.

You must specify a VPC ID in the request.

When you specify multiple parameters, you get instance types that satisfy all of the specified parameters. If you specify multiple values for a parameter, you get instance types that satisfy any of the specified values.

GetInstanceUefiDataCommand

A binary representation of the UEFI variable store. Only non-volatile variables are stored. This is a base64 encoded and zlib compressed binary value that must be properly encoded.

When you use register-image  to create an AMI, you can create an exact copy of your variable store by passing the UEFI data in the UefiData parameter. You can modify the UEFI data by using the python-uefivars tool  on GitHub. You can use the tool to convert the UEFI data into a human-readable format (JSON), which you can inspect and modify, and then convert back into the binary format to use with register-image.

For more information, see UEFI Secure Boot  in the Amazon EC2 User Guide.

GetIpamAddressHistoryCommand

Retrieve historical information about a CIDR within an IPAM scope. For more information, see View the history of IP addresses  in the Amazon VPC IPAM User Guide.

GetIpamDiscoveredAccountsCommand

If you use this action after AllocateIpamPoolCidr  or ReleaseIpamPoolAllocation , note that all EC2 API actions follow an eventual consistency  model.

GetIpamPoolCidrsCommand

Get the CIDRs provisioned to an IPAM pool.

GetIpamResourceCidrsCommand

Returns resource CIDRs managed by IPAM in a given scope. If an IPAM is associated with more than one resource discovery, the resource CIDRs across all of the resource discoveries is returned. A resource discovery is an IPAM component that enables IPAM to manage and monitor resources that belong to the owning account.

GetLaunchTemplateDataCommand

Retrieves the configuration data of the specified instance. You can use this data to create a launch template.

This action calls on other describe actions to get instance information. Depending on your instance configuration, you may need to allow the following actions in your IAM policy: DescribeSpotInstanceRequests, DescribeInstanceCreditSpecifications, DescribeVolumes, and DescribeInstanceAttribute. Or, you can allow describe* depending on your instance requirements.

The Windows password is generated at boot by the EC2Config service or EC2Launch scripts (Windows Server 2016 and later). This usually only happens the first time an instance is launched. For more information, see EC2Config  and EC2Launch  in the Amazon EC2 User Guide.

For the EC2Config service, the password is not generated for rebundled AMIs unless Ec2SetPassword is enabled before bundling.

The password is encrypted using the key pair that you specified when you launched the instance. You must provide the corresponding key pair file.

When you launch an instance, password generation and encryption may take a few minutes. If you try to retrieve the password before it's available, the output returns an empty string. We recommend that you wait up to 15 minutes after launching an instance before trying to retrieve the generated password.

GetReservedInstancesExchangeQuoteCommand

For information about the import manifest referenced by this API action, see VM Import Manifest .

This API action is not supported by the Command Line Interface (CLI).

ListImagesInRecycleBinCommand

Lists one or more AMIs that are currently in the Recycle Bin. For more information, see Recycle Bin  in the Amazon EC2 User Guide.

ListSnapshotsInRecycleBinCommand

Lists one or more snapshots that are currently in the Recycle Bin.

LockSnapshotCommand

Locks an Amazon EBS snapshot in either governance or compliance mode to protect it against accidental or malicious deletions for a specific duration. A locked snapshot can't be deleted.

You can also use this action to modify the lock settings for a snapshot that is already locked. The allowed modifications depend on the lock mode and lock state:

  • If the snapshot is locked in governance mode, you can modify the lock mode and the lock duration or lock expiration date.

  • If the snapshot is locked in compliance mode and it is in the cooling-off period, you can modify the lock mode and the lock duration or lock expiration date.

  • If the snapshot is locked in compliance mode and the cooling-off period has lapsed, you can only increase the lock duration or extend the lock expiration date.

ModifyAddressAttributeCommand

Modifies an attribute of the specified Elastic IP address. For requirements, see Using reverse DNS for email applications .

ModifyAvailabilityZoneGroupCommand

Changes the opt-in status of the specified zone group for your account.

ModifyCapacityReservationCommand

Modifies a Capacity Reservation's capacity, instance eligibility, and the conditions under which it is to be released. You can't modify a Capacity Reservation's instance type, EBS optimization, platform, instance store settings, Availability Zone, or tenancy. If you need to modify any of these attributes, we recommend that you cancel the Capacity Reservation, and then create a new one with the required attributes. For more information, see Modify an active Capacity Reservation .

The allowed modifications depend on the state of the Capacity Reservation:

  • assessing or scheduled state - You can modify the tags only.

  • pending state - You can't modify the Capacity Reservation in any way.

  • active state but still within the commitment duration - You can't decrease the instance count or set an end date that is within the commitment duration. All other modifications are allowed.

  • active state with no commitment duration or elapsed commitment duration - All modifications are allowed.

  • expired, cancelled, unsupported, or failed state - You can't modify the Capacity Reservation in any way.

ModifyCapacityReservationFleetCommand

Modifies a Capacity Reservation Fleet.

When you modify the total target capacity of a Capacity Reservation Fleet, the Fleet automatically creates new Capacity Reservations, or modifies or cancels existing Capacity Reservations in the Fleet to meet the new total target capacity. When you modify the end date for the Fleet, the end dates for all of the individual Capacity Reservations in the Fleet are updated accordingly.

ModifyClientVpnEndpointCommand

Modifies the specified Client VPN endpoint. Modifying the DNS server resets existing client connections.

ModifyDefaultCreditSpecificationCommand

Modifies the default credit option for CPU usage of burstable performance instances. The default credit option is set at the account level per Amazon Web Services Region, and is specified per instance family. All new burstable performance instances in the account launch using the default credit option.

ModifyDefaultCreditSpecification is an asynchronous operation, which works at an Amazon Web Services Region level and modifies the credit option for each Availability Zone. All zones in a Region are updated within five minutes. But if instances are launched during this operation, they might not get the new credit option until the zone is updated. To verify whether the update has occurred, you can call GetDefaultCreditSpecification and check DefaultCreditSpecification for updates.

For more information, see Burstable performance instances  in the Amazon EC2 User Guide.

ModifyEbsDefaultKmsKeyIdCommand

Changes the default KMS key for EBS encryption by default for your account in this Region.

Amazon Web Services creates a unique Amazon Web Services managed KMS key in each Region for use with encryption by default. If you change the default KMS key to a symmetric customer managed KMS key, it is used instead of the Amazon Web Services managed KMS key. To reset the default KMS key to the Amazon Web Services managed KMS key for EBS, use ResetEbsDefaultKmsKeyId. Amazon EBS does not support asymmetric KMS keys.

If you delete or disable the customer managed KMS key that you specified for use with encryption by default, your instances will fail to launch.

For more information, see Amazon EBS encryption  in the Amazon EBS User Guide.

ModifyFleetCommand

Modifies the specified EC2 Fleet.

You can only modify an EC2 Fleet request of type maintain.

While the EC2 Fleet is being modified, it is in the modifying state.

To scale up your EC2 Fleet, increase its target capacity. The EC2 Fleet launches the additional Spot Instances according to the allocation strategy for the EC2 Fleet request. If the allocation strategy is lowest-price, the EC2 Fleet launches instances using the Spot Instance pool with the lowest price. If the allocation strategy is diversified, the EC2 Fleet distributes the instances across the Spot Instance pools. If the allocation strategy is capacity-optimized, EC2 Fleet launches instances from Spot Instance pools with optimal capacity for the number of instances that are launching.

To scale down your EC2 Fleet, decrease its target capacity. First, the EC2 Fleet cancels any open requests that exceed the new target capacity. You can request that the EC2 Fleet terminate Spot Instances until the size of the fleet no longer exceeds the new target capacity. If the allocation strategy is lowest-price, the EC2 Fleet terminates the instances with the highest price per unit. If the allocation strategy is capacity-optimized, the EC2 Fleet terminates the instances in the Spot Instance pools that have the least available Spot Instance capacity. If the allocation strategy is diversified, the EC2 Fleet terminates instances across the Spot Instance pools. Alternatively, you can request that the EC2 Fleet keep the fleet at its current size, but not replace any Spot Instances that are interrupted or that you terminate manually.

If you are finished with your EC2 Fleet for now, but will use it again later, you can set the target capacity to 0.

ModifyFpgaImageAttributeCommand

Modifies the specified attribute of the specified Amazon FPGA Image (AFI).

ModifyHostsCommand

Modify the auto-placement setting of a Dedicated Host. When auto-placement is enabled, any instances that you launch with a tenancy of host but without a specific host ID are placed onto any available Dedicated Host in your account that has auto-placement enabled. When auto-placement is disabled, you need to provide a host ID to have the instance launch onto a specific host. If no host ID is provided, the instance is launched onto a suitable host with auto-placement enabled.

You can also use this API action to modify a Dedicated Host to support either multiple instance types in an instance family, or to support a specific instance type only.

ModifyIdFormatCommand

Modifies the ID format for the specified resource on a per-Region basis. You can specify that resources should receive longer IDs (17-character IDs) when they are created.

This request can only be used to modify longer ID settings for resource types that are within the opt-in period.

This setting applies to the IAM user who makes the request; it does not apply to the entire Amazon Web Services account. By default, an IAM user defaults to the same settings as the root user. If you're using this action as the root user, then these settings apply to the entire account, unless an IAM user explicitly overrides these settings for themselves. For more information, see Resource IDs  in the Amazon Elastic Compute Cloud User Guide.

Resources created with longer IDs are visible to all IAM roles and users, regardless of these settings and provided that they have permission to use the relevant Describe command for the resource type.

ModifyIdentityIdFormatCommand

Modifies the ID format of a resource for a specified IAM user, IAM role, or the root user for an account; or all IAM users, IAM roles, and the root user for an account. You can specify that resources should receive longer IDs (17-character IDs) when they are created.

This request can only be used to modify longer ID settings for resource types that are within the opt-in period. Resources currently in their opt-in period include: bundle | conversion-task | customer-gateway | dhcp-options | elastic-ip-allocation | elastic-ip-association | export-task | flow-log | image | import-task | internet-gateway | network-acl | network-acl-association | network-interface | network-interface-attachment | prefix-list | route-table | route-table-association | security-group | subnet | subnet-cidr-block-association | vpc | vpc-cidr-block-association | vpc-endpoint | vpc-peering-connection | vpn-connection | vpn-gateway.

For more information, see Resource IDs  in the Amazon Elastic Compute Cloud User Guide.

This setting applies to the principal specified in the request; it does not apply to the principal that makes the request.

Resources created with longer IDs are visible to all IAM roles and users, regardless of these settings and provided that they have permission to use the relevant Describe command for the resource type.

ModifyImageAttributeCommand

Modifies the specified attribute of the specified AMI. You can specify only one attribute at a time.

To specify the attribute, you can use the Attribute parameter, or one of the following parameters: Description, ImdsSupport, or LaunchPermission.

Images with an Amazon Web Services Marketplace product code cannot be made public.

To enable the SriovNetSupport enhanced networking attribute of an image, enable SriovNetSupport on an instance and create an AMI from the instance.

ModifyInstanceAttributeCommand

Modifies the specified attribute of the specified instance. You can specify only one attribute at a time.

Note: Using this action to change the security groups associated with an elastic network interface (ENI) attached to an instance can result in an error if the instance has more than one ENI. To change the security groups associated with an ENI attached to an instance that has multiple ENIs, we recommend that you use the ModifyNetworkInterfaceAttribute action.

To modify some attributes, the instance must be stopped. For more information, see Modify a stopped instance  in the Amazon EC2 User Guide.

ModifyInstanceCapacityReservationAttributesCommand

Modifies the Capacity Reservation settings for a stopped instance. Use this action to configure an instance to target a specific Capacity Reservation, run in any open Capacity Reservation with matching attributes, run in On-Demand Instance capacity, or only run in a Capacity Reservation.

ModifyInstanceCpuOptionsCommand

By default, all vCPUs for the instance type are active when you launch an instance. When you configure the number of active vCPUs for the instance, it can help you save on licensing costs and optimize performance. The base cost of the instance remains unchanged.

The number of active vCPUs equals the number of threads per CPU core multiplied by the number of cores. The instance must be in a Stopped state before you make changes.

Some instance type options do not support this capability. For more information, see Supported CPU options  in the Amazon EC2 User Guide.

ModifyInstanceCreditSpecificationCommand

Modifies the credit option for CPU usage on a running or stopped burstable performance instance. The credit options are standard and unlimited.

For more information, see Burstable performance instances  in the Amazon EC2 User Guide.

ModifyInstanceEventStartTimeCommand

Modifies the start time for a scheduled Amazon EC2 instance event.

ModifyInstanceEventWindowCommand

Modifies the specified event window.

You can define either a set of time ranges or a cron expression when modifying the event window, but not both.

To modify the targets associated with the event window, use the AssociateInstanceEventWindow and DisassociateInstanceEventWindow API.

If Amazon Web Services has already scheduled an event, modifying an event window won't change the time of the scheduled event.

For more information, see Define event windows for scheduled events  in the Amazon EC2 User Guide.

ModifyInstanceMaintenanceOptionsCommand

Modifies the recovery behavior of your instance to disable simplified automatic recovery or set the recovery behavior to default. The default configuration will not enable simplified automatic recovery for an unsupported instance type. For more information, see Simplified automatic recovery .

ModifyInstanceMetadataDefaultsCommand

Modifies the default instance metadata service (IMDS) settings at the account level in the specified Amazon Web Services Region.

To remove a parameter's account-level default setting, specify no-preference. If an account-level setting is cleared with no-preference, then the instance launch considers the other instance metadata settings. For more information, see Order of precedence for instance metadata options  in the Amazon EC2 User Guide.

ModifyInstanceMetadataOptionsCommand

Modify the instance metadata parameters on a running or stopped instance. When you modify the parameters on a stopped instance, they are applied when the instance is started. When you modify the parameters on a running instance, the API responds with a state of “pending”. After the parameter modifications are successfully applied to the instance, the state of the modifications changes from “pending” to “applied” in subsequent describe-instances API calls. For more information, see Instance metadata and user data  in the Amazon EC2 User Guide.

ModifyInstanceNetworkPerformanceOptionsCommand

Change the configuration of the network performance options for an existing instance.

ModifyInstancePlacementCommand

Modifies the placement attributes for a specified instance. You can do the following:

  • Modify the affinity between an instance and a Dedicated Host . When affinity is set to host and the instance is not associated with a specific Dedicated Host, the next time the instance is started, it is automatically associated with the host on which it lands. If the instance is restarted or rebooted, this relationship persists.

  • Change the Dedicated Host with which an instance is associated.

  • Change the instance tenancy of an instance.

  • Move an instance to or from a placement group .

At least one attribute for affinity, host ID, tenancy, or placement group name must be specified in the request. Affinity and tenancy can be modified in the same request.

To modify the host ID, tenancy, placement group, or partition for an instance, the instance must be in the stopped state.

ModifyIpamCommand

Modify the configurations of an IPAM.

ModifyIpamPoolCommand

Modify the configurations of an IPAM pool.

For more information, see Modify a pool  in the Amazon VPC IPAM User Guide.

ModifyIpamResourceCidrCommand

Modify a resource CIDR. You can use this action to transfer resource CIDRs between scopes and ignore resource CIDRs that you do not want to manage. If set to false, the resource will not be tracked for overlap, it cannot be auto-imported into a pool, and it will be removed from any pool it has an allocation in.

For more information, see Move resource CIDRs between scopes  and Change the monitoring state of resource CIDRs  in the Amazon VPC IPAM User Guide.

ModifyIpamResourceDiscoveryCommand

Modifies a resource discovery. A resource discovery is an IPAM component that enables IPAM to manage and monitor resources that belong to the owning account.

ModifyIpamScopeCommand

Modify an IPAM scope.

ModifyLaunchTemplateCommand

Modifies a launch template. You can specify which version of the launch template to set as the default version. When launching an instance, the default version applies when a launch template version is not specified.

ModifyLocalGatewayRouteCommand

Modifies the specified local gateway route.

ModifyManagedPrefixListCommand

Modifies the specified managed prefix list.

Adding or removing entries in a prefix list creates a new version of the prefix list. Changing the name of the prefix list does not affect the version.

If you specify a current version number that does not match the true current version number, the request fails.

ModifyNetworkInterfaceAttributeCommand

Modifies the specified network interface attribute. You can specify only one attribute at a time. You can use this action to attach and detach security groups from an existing EC2 instance.

ModifyPrivateDnsNameOptionsCommand

Modifies the options for instance hostnames for the specified instance.

ModifyReservedInstancesCommand

Modifies the configuration of your Reserved Instances, such as the Availability Zone, instance count, or instance type. The Reserved Instances to be modified must be identical, except for Availability Zone, network platform, and instance type.

For more information, see Modify Reserved Instances  in the Amazon EC2 User Guide.

ModifySecurityGroupRulesCommand

Modifies the rules of a security group.

ModifySnapshotAttributeCommand

Adds or removes permission settings for the specified snapshot. You may add or remove specified Amazon Web Services account IDs from a snapshot's list of create volume permissions, but you cannot do both in a single operation. If you need to both add and remove account IDs for a snapshot, you must use multiple operations. You can make up to 500 modifications to a snapshot in a single operation.

Encrypted snapshots and snapshots with Amazon Web Services Marketplace product codes cannot be made public. Snapshots encrypted with your default KMS key cannot be shared with other accounts.

For more information about modifying snapshot permissions, see Share a snapshot  in the Amazon EBS User Guide.

ModifySnapshotTierCommand

Archives an Amazon EBS snapshot. When you archive a snapshot, it is converted to a full snapshot that includes all of the blocks of data that were written to the volume at the time the snapshot was created, and moved from the standard tier to the archive tier. For more information, see Archive Amazon EBS snapshots  in the Amazon EBS User Guide.

ModifySpotFleetRequestCommand

Modifies the specified Spot Fleet request.

You can only modify a Spot Fleet request of type maintain.

While the Spot Fleet request is being modified, it is in the modifying state.

To scale up your Spot Fleet, increase its target capacity. The Spot Fleet launches the additional Spot Instances according to the allocation strategy for the Spot Fleet request. If the allocation strategy is lowestPrice, the Spot Fleet launches instances using the Spot Instance pool with the lowest price. If the allocation strategy is diversified, the Spot Fleet distributes the instances across the Spot Instance pools. If the allocation strategy is capacityOptimized, Spot Fleet launches instances from Spot Instance pools with optimal capacity for the number of instances that are launching.

To scale down your Spot Fleet, decrease its target capacity. First, the Spot Fleet cancels any open requests that exceed the new target capacity. You can request that the Spot Fleet terminate Spot Instances until the size of the fleet no longer exceeds the new target capacity. If the allocation strategy is lowestPrice, the Spot Fleet terminates the instances with the highest price per unit. If the allocation strategy is capacityOptimized, the Spot Fleet terminates the instances in the Spot Instance pools that have the least available Spot Instance capacity. If the allocation strategy is diversified, the Spot Fleet terminates instances across the Spot Instance pools. Alternatively, you can request that the Spot Fleet keep the fleet at its current size, but not replace any Spot Instances that are interrupted or that you terminate manually.

If you are finished with your Spot Fleet for now, but will use it again later, you can set the target capacity to 0.

ModifySubnetAttributeCommand

Modifies a subnet attribute. You can only modify one attribute at a time.

Use this action to modify subnets on Amazon Web Services Outposts.

  • To modify a subnet on an Outpost rack, set both MapCustomerOwnedIpOnLaunch and CustomerOwnedIpv4Pool. These two parameters act as a single attribute.

  • To modify a subnet on an Outpost server, set either EnableLniAtDeviceIndex or DisableLniAtDeviceIndex.

For more information about Amazon Web Services Outposts, see the following:

ModifyTrafficMirrorFilterNetworkServicesCommand

Allows or restricts mirroring network services.

By default, Amazon DNS network services are not eligible for Traffic Mirror. Use AddNetworkServices to add network services to a Traffic Mirror filter. When a network service is added to the Traffic Mirror filter, all traffic related to that network service will be mirrored. When you no longer want to mirror network services, use RemoveNetworkServices to remove the network services from the Traffic Mirror filter.

ModifyTrafficMirrorFilterRuleCommand

Modifies the specified Traffic Mirror rule.

DestinationCidrBlock and SourceCidrBlock must both be an IPv4 range or an IPv6 range.

ModifyTrafficMirrorSessionCommand

Modifies a Traffic Mirror session.

ModifyTransitGatewayCommand

Modifies the specified transit gateway. When you modify a transit gateway, the modified options are applied to new transit gateway attachments only. Your existing transit gateway attachments are not modified.

ModifyVerifiedAccessInstanceLoggingConfigurationCommand

Modifies the logging configuration for the specified Amazon Web Services Verified Access instance.

ModifyVerifiedAccessTrustProviderCommand

Modifies the configuration of the specified Amazon Web Services Verified Access trust provider.

ModifyVolumeAttributeCommand

Modifies a volume attribute.

By default, all I/O operations for the volume are suspended when the data on the volume is determined to be potentially inconsistent, to prevent undetectable, latent data corruption. The I/O access to the volume can be resumed by first enabling I/O access and then checking the data consistency on your volume.

You can change the default behavior to resume I/O operations. We recommend that you change this only for boot volumes or for volumes that are stateless or disposable.

ModifyVolumeCommand

You can modify several parameters of an existing EBS volume, including volume size, volume type, and IOPS capacity. If your EBS volume is attached to a current-generation EC2 instance type, you might be able to apply these changes without stopping the instance or detaching the volume from it. For more information about modifying EBS volumes, see Amazon EBS Elastic Volumes  in the Amazon EBS User Guide.

When you complete a resize operation on your volume, you need to extend the volume's file-system size to take advantage of the new storage capacity. For more information, see Extend the file system .

For more information, see Monitor the progress of volume modifications  in the Amazon EBS User Guide.

With previous-generation instance types, resizing an EBS volume might require detaching and reattaching the volume or stopping and restarting the instance.

After modifying a volume, you must wait at least six hours and ensure that the volume is in the in-use or available state before you can modify the same volume. This is sometimes referred to as a cooldown period.

ModifyVpcAttributeCommand

Modifies the specified attribute of the specified VPC.

ModifyVpcBlockPublicAccessExclusionCommand

Modify VPC Block Public Access (BPA) exclusions. A VPC BPA exclusion is a mode that can be applied to a single VPC or subnet that exempts it from the account’s BPA mode and will allow bidirectional or egress-only access. You can create BPA exclusions for VPCs and subnets even when BPA is not enabled on the account to ensure that there is no traffic disruption to the exclusions when VPC BPA is turned on.

ModifyVpcBlockPublicAccessOptionsCommand

Modify VPC Block Public Access (BPA) options. VPC Block Public Access (BPA) enables you to block resources in VPCs and subnets that you own in a Region from reaching or being reached from the internet through internet gateways and egress-only internet gateways. To learn more about VPC BPA, see Block public access to VPCs and subnets  in the Amazon VPC User Guide.

ModifyVpcEndpointCommand

Modifies attributes of a specified VPC endpoint. The attributes that you can modify depend on the type of VPC endpoint (interface, gateway, or Gateway Load Balancer). For more information, see the Amazon Web Services PrivateLink Guide .

ModifyVpcEndpointConnectionNotificationCommand

Modifies a connection notification for VPC endpoint or VPC endpoint service. You can change the SNS topic for the notification, or the events for which to be notified.

ModifyVpcEndpointServiceConfigurationCommand

Modifies the attributes of the specified VPC endpoint service configuration.

If you set or modify the private DNS name, you must prove that you own the private DNS domain name.

ModifyVpcEndpointServicePayerResponsibilityCommand

Modifies the payer responsibility for your VPC endpoint service.

ModifyVpcEndpointServicePermissionsCommand

Modifies the permissions for your VPC endpoint service. You can add or remove permissions for service consumers (Amazon Web Services accounts, users, and IAM roles) to connect to your endpoint service.

If you grant permissions to all principals, the service is public. Any users who know the name of a public service can send a request to attach an endpoint. If the service does not require manual approval, attachments are automatically approved.

ModifyVpcPeeringConnectionOptionsCommand

Modifies the VPC peering connection options on one side of a VPC peering connection.

If the peered VPCs are in the same Amazon Web Services account, you can enable DNS resolution for queries from the local VPC. This ensures that queries from the local VPC resolve to private IP addresses in the peer VPC. This option is not available if the peered VPCs are in different Amazon Web Services accounts or different Regions. For peered VPCs in different Amazon Web Services accounts, each Amazon Web Services account owner must initiate a separate request to modify the peering connection options. For inter-region peering connections, you must use the Region for the requester VPC to modify the requester VPC peering options and the Region for the accepter VPC to modify the accepter VPC peering options. To verify which VPCs are the accepter and the requester for a VPC peering connection, use the DescribeVpcPeeringConnections command.

ModifyVpcTenancyCommand

Modifies the instance tenancy attribute of the specified VPC. You can change the instance tenancy attribute of a VPC to default only. You cannot change the instance tenancy attribute to dedicated.

After you modify the tenancy of the VPC, any new instances that you launch into the VPC have a tenancy of default, unless you specify otherwise during launch. The tenancy of any existing instances in the VPC is not affected.

For more information, see Dedicated Instances  in the Amazon EC2 User Guide.

ModifyVpnConnectionCommand

Modifies the customer gateway or the target gateway of an Amazon Web Services Site-to-Site VPN connection. To modify the target gateway, the following migration options are available:

  • An existing virtual private gateway to a new virtual private gateway

  • An existing virtual private gateway to a transit gateway

  • An existing transit gateway to a new transit gateway

  • An existing transit gateway to a virtual private gateway

Before you perform the migration to the new gateway, you must configure the new gateway. Use CreateVpnGateway to create a virtual private gateway, or CreateTransitGateway to create a transit gateway.

This step is required when you migrate from a virtual private gateway with static routes to a transit gateway.

You must delete the static routes before you migrate to the new gateway.

Keep a copy of the static route before you delete it. You will need to add back these routes to the transit gateway after the VPN connection migration is complete.

After you migrate to the new gateway, you might need to modify your VPC route table. Use CreateRoute and DeleteRoute to make the changes described in Update VPC route tables  in the Amazon Web Services Site-to-Site VPN User Guide.

When the new gateway is a transit gateway, modify the transit gateway route table to allow traffic between the VPC and the Amazon Web Services Site-to-Site VPN connection. Use CreateTransitGatewayRoute to add the routes.

If you deleted VPN static routes, you must add the static routes to the transit gateway route table.

After you perform this operation, the VPN endpoint's IP addresses on the Amazon Web Services side and the tunnel options remain intact. Your Amazon Web Services Site-to-Site VPN connection will be temporarily unavailable for a brief period while we provision the new endpoints.

ModifyVpnConnectionOptionsCommand

Modifies the connection options for your Site-to-Site VPN connection.

When you modify the VPN connection options, the VPN endpoint IP addresses on the Amazon Web Services side do not change, and the tunnel options do not change. Your VPN connection will be temporarily unavailable for a brief period while the VPN connection is updated.

ModifyVpnTunnelCertificateCommand

Modifies the VPN tunnel endpoint certificate.

ModifyVpnTunnelOptionsCommand

Modifies the options for a VPN tunnel in an Amazon Web Services Site-to-Site VPN connection. You can modify multiple options for a tunnel in a single request, but you can only modify one tunnel at a time. For more information, see Site-to-Site VPN tunnel options for your Site-to-Site VPN connection  in the Amazon Web Services Site-to-Site VPN User Guide.

MonitorInstancesCommand

Enables detailed monitoring for a running instance. Otherwise, basic monitoring is enabled. For more information, see Monitor your instances using CloudWatch  in the Amazon EC2 User Guide.

To disable detailed monitoring, see UnmonitorInstances .

MoveAddressToVpcCommand

This action is deprecated.

Moves an Elastic IP address from the EC2-Classic platform to the EC2-VPC platform. The Elastic IP address must be allocated to your account for more than 24 hours, and it must not be associated with an instance. After the Elastic IP address is moved, it is no longer available for use in the EC2-Classic platform, unless you move it back using the RestoreAddressToClassic request. You cannot move an Elastic IP address that was originally allocated for use in the EC2-VPC platform to the EC2-Classic platform.

MoveByoipCidrToIpamCommand

Move a BYOIPv4 CIDR to IPAM from a public IPv4 pool.

If you already have a BYOIPv4 CIDR with Amazon Web Services, you can move the CIDR to IPAM from a public IPv4 pool. You cannot move an IPv6 CIDR to IPAM. If you are bringing a new IP address to Amazon Web Services for the first time, complete the steps in Tutorial: BYOIP address CIDRs to IPAM .

MoveCapacityReservationInstancesCommand

Move available capacity from a source Capacity Reservation to a destination Capacity Reservation. The source Capacity Reservation and the destination Capacity Reservation must be active, owned by your Amazon Web Services account, and share the following:

  • Instance type

  • Platform

  • Availability Zone

  • Tenancy

  • Placement group

  • Capacity Reservation end time - At specific time or Manually.

ProvisionByoipCidrCommand

Provisions an IPv4 or IPv6 address range for use with your Amazon Web Services resources through bring your own IP addresses (BYOIP) and creates a corresponding address pool. After the address range is provisioned, it is ready to be advertised using AdvertiseByoipCidr.

Amazon Web Services verifies that you own the address range and are authorized to advertise it. You must ensure that the address range is registered to you and that you created an RPKI ROA to authorize Amazon ASNs 16509 and 14618 to advertise the address range. For more information, see Bring your own IP addresses (BYOIP)  in the Amazon EC2 User Guide.

Provisioning an address range is an asynchronous operation, so the call returns immediately, but the address range is not ready to use until its status changes from pending-provision to provisioned. To monitor the status of an address range, use DescribeByoipCidrs. To allocate an Elastic IP address from your IPv4 address pool, use AllocateAddress with either the specific address from the address pool or the ID of the address pool.

ProvisionIpamByoasnCommand

Provisions your Autonomous System Number (ASN) for use in your Amazon Web Services account. This action requires authorization context for Amazon to bring the ASN to an Amazon Web Services account. For more information, see Tutorial: Bring your ASN to IPAM  in the Amazon VPC IPAM guide.

ProvisionIpamPoolCidrCommand

Provision a CIDR to an IPAM pool. You can use this action to provision new CIDRs to a top-level pool or to transfer a CIDR from a top-level pool to a pool within it.

For more information, see Provision CIDRs to pools  in the Amazon VPC IPAM User Guide.

ProvisionPublicIpv4PoolCidrCommand

Provision a CIDR to a public IPv4 pool.

For more information about IPAM, see What is IPAM?  in the Amazon VPC IPAM User Guide.

PurchaseCapacityBlockCommand

Purchase the Capacity Block for use with your account. With Capacity Blocks you ensure GPU capacity is available for machine learning (ML) workloads. You must specify the ID of the Capacity Block offering you are purchasing.

PurchaseCapacityBlockExtensionCommand

Purchase the Capacity Block extension for use with your account. You must specify the ID of the Capacity Block extension offering you are purchasing.

PurchaseHostReservationCommand

Purchase a reservation with configurations that match those of your Dedicated Host. You must have active Dedicated Hosts in your account before you purchase a reservation. This action results in the specified reservation being purchased and charged to your account.

PurchaseReservedInstancesOfferingCommand

Purchases a Reserved Instance for use with your account. With Reserved Instances, you pay a lower hourly rate compared to On-Demand instance pricing.

Use DescribeReservedInstancesOfferings to get a list of Reserved Instance offerings that match your specifications. After you've purchased a Reserved Instance, you can check for your new Reserved Instance with DescribeReservedInstances.

To queue a purchase for a future date and time, specify a purchase time. If you do not specify a purchase time, the default is the current time.

For more information, see Reserved Instances  and Sell in the Reserved Instance Marketplace  in the Amazon EC2 User Guide.

PurchaseScheduledInstancesCommand

You can no longer purchase Scheduled Instances.

Purchases the Scheduled Instances with the specified schedule.

Scheduled Instances enable you to purchase Amazon EC2 compute capacity by the hour for a one-year term. Before you can purchase a Scheduled Instance, you must call DescribeScheduledInstanceAvailability to check for available schedules and obtain a purchase token. After you purchase a Scheduled Instance, you must call RunScheduledInstances during each scheduled time period.

After you purchase a Scheduled Instance, you can't cancel, modify, or resell your purchase.

RebootInstancesCommand

Requests a reboot of the specified instances. This operation is asynchronous; it only queues a request to reboot the specified instances. The operation succeeds if the instances are valid and belong to you. Requests to reboot terminated instances are ignored.

If an instance does not cleanly shut down within a few minutes, Amazon EC2 performs a hard reboot.

For more information about troubleshooting, see Troubleshoot an unreachable instance  in the Amazon EC2 User Guide.

RegisterImageCommand

Registers an AMI. When you're creating an instance-store backed AMI, registering the AMI is the final step in the creation process. For more information about creating AMIs, see Create an AMI from a snapshot  and Create an instance-store backed AMI  in the Amazon EC2 User Guide.

For Amazon EBS-backed instances, CreateImage creates and registers the AMI in a single request, so you don't have to register the AMI yourself. We recommend that you always use CreateImage unless you have a specific reason to use RegisterImage.

If needed, you can deregister an AMI at any time. Any modifications you make to an AMI backed by an instance store volume invalidates its registration. If you make changes to an image, deregister the previous image and register the new image.

Register a snapshot of a root device volume

You can use RegisterImage to create an Amazon EBS-backed Linux AMI from a snapshot of a root device volume. You specify the snapshot using a block device mapping. You can't set the encryption state of the volume using the block device mapping. If the snapshot is encrypted, or encryption by default is enabled, the root volume of an instance launched from the AMI is encrypted.

For more information, see Create an AMI from a snapshot  and Use encryption with Amazon EBS-backed AMIs  in the Amazon EC2 User Guide.

Amazon Web Services Marketplace product codes

If any snapshots have Amazon Web Services Marketplace product codes, they are copied to the new AMI.

In most cases, AMIs for Windows, RedHat, SUSE, and SQL Server require correct licensing information to be present on the AMI. For more information, see Understand AMI billing information  in the Amazon EC2 User Guide. When creating an AMI from a snapshot, the RegisterImage operation derives the correct billing information from the snapshot's metadata, but this requires the appropriate metadata to be present. To verify if the correct billing information was applied, check the PlatformDetails field on the new AMI. If the field is empty or doesn't match the expected operating system code (for example, Windows, RedHat, SUSE, or SQL), the AMI creation was unsuccessful, and you should discard the AMI and instead create the AMI from an instance using CreateImage. For more information, see Create an AMI from an instance   in the Amazon EC2 User Guide.

If you purchase a Reserved Instance to apply to an On-Demand Instance that was launched from an AMI with a billing product code, make sure that the Reserved Instance has the matching billing product code. If you purchase a Reserved Instance without the matching billing product code, the Reserved Instance will not be applied to the On-Demand Instance. For information about how to obtain the platform details and billing information of an AMI, see Understand AMI billing information  in the Amazon EC2 User Guide.

RegisterInstanceEventNotificationAttributesCommand

Registers a set of tag keys to include in scheduled event notifications for your resources.

RegisterTransitGatewayMulticastGroupMembersCommand

Registers members (network interfaces) with the transit gateway multicast group. A member is a network interface associated with a supported EC2 instance that receives multicast traffic. For more information, see Multicast on transit gateways  in the Amazon Web Services Transit Gateways Guide.

After you add the members, use SearchTransitGatewayMulticastGroups  to verify that the members were added to the transit gateway multicast group.

RegisterTransitGatewayMulticastGroupSourcesCommand

Registers sources (network interfaces) with the specified transit gateway multicast group.

A multicast source is a network interface attached to a supported instance that sends multicast traffic. For more information about supported instances, see Multicast on transit gateways  in the Amazon Web Services Transit Gateways Guide.

After you add the source, use SearchTransitGatewayMulticastGroups  to verify that the source was added to the multicast group.

RejectCapacityReservationBillingOwnershipCommand

Rejects a request to assign billing of the available capacity of a shared Capacity Reservation to your account. For more information, see Billing assignment for shared Amazon EC2 Capacity Reservations .

RejectTransitGatewayMulticastDomainAssociationsCommand

Rejects a request to associate cross-account subnets with a transit gateway multicast domain.

RejectTransitGatewayPeeringAttachmentCommand

Rejects a transit gateway peering attachment request.

RejectTransitGatewayVpcAttachmentCommand

Rejects a request to attach a VPC to a transit gateway.

The VPC attachment must be in the pendingAcceptance state. Use DescribeTransitGatewayVpcAttachments to view your pending VPC attachment requests. Use AcceptTransitGatewayVpcAttachment to accept a VPC attachment request.

RejectVpcEndpointConnectionsCommand

Rejects VPC endpoint connection requests to your VPC endpoint service.

RejectVpcPeeringConnectionCommand

Rejects a VPC peering connection request. The VPC peering connection must be in the pending-acceptance state. Use the DescribeVpcPeeringConnections request to view your outstanding VPC peering connection requests. To delete an active VPC peering connection, or to delete a VPC peering connection request that you initiated, use DeleteVpcPeeringConnection.

ReleaseAddressCommand

Releases the specified Elastic IP address.

[Default VPC] Releasing an Elastic IP address automatically disassociates it from any instance that it's associated with. To disassociate an Elastic IP address without releasing it, use DisassociateAddress.

[Nondefault VPC] You must use DisassociateAddress to disassociate the Elastic IP address before you can release it. Otherwise, Amazon EC2 returns an error (InvalidIPAddress.InUse).

After releasing an Elastic IP address, it is released to the IP address pool. Be sure to update your DNS records and any servers or devices that communicate with the address. If you attempt to release an Elastic IP address that you already released, you'll get an AuthFailure error if the address is already allocated to another Amazon Web Services account.

After you release an Elastic IP address, you might be able to recover it. For more information, see AllocateAddress.

ReleaseHostsCommand

When you no longer want to use an On-Demand Dedicated Host it can be released. On-Demand billing is stopped and the host goes into released state. The host ID of Dedicated Hosts that have been released can no longer be specified in another request, for example, to modify the host. You must stop or terminate all instances on a host before it can be released.

When Dedicated Hosts are released, it may take some time for them to stop counting toward your limit and you may receive capacity errors when trying to allocate new Dedicated Hosts. Wait a few minutes and then try again.

Released hosts still appear in a DescribeHosts response.

ReleaseIpamPoolAllocationCommand

Release an allocation within an IPAM pool. The Region you use should be the IPAM pool locale. The locale is the Amazon Web Services Region where this IPAM pool is available for allocations. You can only use this action to release manual allocations. To remove an allocation for a resource without deleting the resource, set its monitored state to false using ModifyIpamResourceCidr . For more information, see Release an allocation  in the Amazon VPC IPAM User Guide.

All EC2 API actions follow an eventual consistency  model.

ReplaceIamInstanceProfileAssociationCommand

Replaces an IAM instance profile for the specified running instance. You can use this action to change the IAM instance profile that's associated with an instance without having to disassociate the existing IAM instance profile first.

Use DescribeIamInstanceProfileAssociations to get the association ID.

ReplaceImageCriteriaInAllowedImagesSettingsCommand

Sets or replaces the criteria for Allowed AMIs.

The Allowed AMIs feature does not restrict the AMIs owned by your account. Regardless of the criteria you set, the AMIs created by your account will always be discoverable and usable by users in your account.

For more information, see Control the discovery and use of AMIs in Amazon EC2 with Allowed AMIs  in Amazon EC2 User Guide.

ReplaceNetworkAclAssociationCommand

Changes which network ACL a subnet is associated with. By default when you create a subnet, it's automatically associated with the default network ACL. For more information, see Network ACLs  in the Amazon VPC User Guide.

This is an idempotent operation.

ReplaceNetworkAclEntryCommand

Replaces an entry (rule) in a network ACL. For more information, see Network ACLs  in the Amazon VPC User Guide.

ReplaceRouteCommand

Replaces an existing route within a route table in a VPC.

You must specify either a destination CIDR block or a prefix list ID. You must also specify exactly one of the resources from the parameter list, or reset the local route to its default target.

For more information, see Route tables  in the Amazon VPC User Guide.

ReplaceRouteTableAssociationCommand

Changes the route table associated with a given subnet, internet gateway, or virtual private gateway in a VPC. After the operation completes, the subnet or gateway uses the routes in the new route table. For more information about route tables, see Route tables  in the Amazon VPC User Guide.

You can also use this operation to change which table is the main route table in the VPC. Specify the main route table's association ID and the route table ID of the new main route table.

ReplaceTransitGatewayRouteCommand

Replaces the specified route in the specified transit gateway route table.

ReplaceVpnTunnelCommand

Trigger replacement of specified VPN tunnel.

ReportInstanceStatusCommand

Submits feedback about the status of an instance. The instance must be in the running state. If your experience with the instance differs from the instance status returned by DescribeInstanceStatus, use ReportInstanceStatus to report your experience with the instance. Amazon EC2 collects this information to improve the accuracy of status checks.

Use of this action does not change the value returned by DescribeInstanceStatus.

RequestSpotFleetCommand

Creates a Spot Fleet request.

The Spot Fleet request specifies the total target capacity and the On-Demand target capacity. Amazon EC2 calculates the difference between the total capacity and On-Demand capacity, and launches the difference as Spot capacity.

You can submit a single request that includes multiple launch specifications that vary by instance type, AMI, Availability Zone, or subnet.

By default, the Spot Fleet requests Spot Instances in the Spot Instance pool where the price per unit is the lowest. Each launch specification can include its own instance weighting that reflects the value of the instance type to your application workload.

Alternatively, you can specify that the Spot Fleet distribute the target capacity across the Spot pools included in its launch specifications. By ensuring that the Spot Instances in your Spot Fleet are in different Spot pools, you can improve the availability of your fleet.

You can specify tags for the Spot Fleet request and instances launched by the fleet. You cannot tag other resource types in a Spot Fleet request because only the spot-fleet-request and instance resource types are supported.

For more information, see Spot Fleet requests  in the Amazon EC2 User Guide.

We strongly discourage using the RequestSpotFleet API because it is a legacy API with no planned investment. For options for requesting Spot Instances, see Which is the best Spot request method to use?  in the Amazon EC2 User Guide.

RequestSpotInstancesCommand

Creates a Spot Instance request.

For more information, see Work with Spot Instance  in the Amazon EC2 User Guide.

We strongly discourage using the RequestSpotInstances API because it is a legacy API with no planned investment. For options for requesting Spot Instances, see Which is the best Spot request method to use?  in the Amazon EC2 User Guide.

ResetAddressAttributeCommand

Resets the attribute of the specified IP address. For requirements, see Using reverse DNS for email applications .

ResetEbsDefaultKmsKeyIdCommand

Resets the default KMS key for EBS encryption for your account in this Region to the Amazon Web Services managed KMS key for EBS.

After resetting the default KMS key to the Amazon Web Services managed KMS key, you can continue to encrypt by a customer managed KMS key by specifying it when you create the volume. For more information, see Amazon EBS encryption  in the Amazon EBS User Guide.

ResetFpgaImageAttributeCommand

Resets the specified attribute of the specified Amazon FPGA Image (AFI) to its default value. You can only reset the load permission attribute.

ResetImageAttributeCommand

Resets an attribute of an AMI to its default value.

ResetInstanceAttributeCommand

Resets an attribute of an instance to its default value. To reset the kernel or ramdisk, the instance must be in a stopped state. To reset the sourceDestCheck, the instance can be either running or stopped.

The sourceDestCheck attribute controls whether source/destination checking is enabled. The default value is true, which means checking is enabled. This value must be false for a NAT instance to perform NAT. For more information, see NAT instances  in the Amazon VPC User Guide.

ResetNetworkInterfaceAttributeCommand

Resets a network interface attribute. You can specify only one attribute at a time.

ResetSnapshotAttributeCommand

Resets permission settings for the specified snapshot.

For more information about modifying snapshot permissions, see Share a snapshot  in the Amazon EBS User Guide.

RestoreAddressToClassicCommand

This action is deprecated.

Restores an Elastic IP address that was previously moved to the EC2-VPC platform back to the EC2-Classic platform. You cannot move an Elastic IP address that was originally allocated for use in EC2-VPC. The Elastic IP address must not be associated with an instance or network interface.

RestoreImageFromRecycleBinCommand

Restores an AMI from the Recycle Bin. For more information, see Recycle Bin  in the Amazon EC2 User Guide.

RestoreManagedPrefixListVersionCommand

Restores the entries from a previous version of a managed prefix list to a new version of the prefix list.

RestoreSnapshotFromRecycleBinCommand

Restores a snapshot from the Recycle Bin. For more information, see Restore snapshots from the Recycle Bin  in the Amazon EBS User Guide.

RestoreSnapshotTierCommand

Restores an archived Amazon EBS snapshot for use temporarily or permanently, or modifies the restore period or restore type for a snapshot that was previously temporarily restored.

RevokeClientVpnIngressCommand

Removes an ingress authorization rule from a Client VPN endpoint.

RevokeSecurityGroupEgressCommand

Removes the specified outbound (egress) rules from the specified security group.

You can specify rules using either rule IDs or security group rule properties. If you use rule properties, the values that you specify (for example, ports) must match the existing rule's values exactly. Each rule has a protocol, from and to ports, and destination (CIDR range, security group, or prefix list). For the TCP and UDP protocols, you must also specify the destination port or range of ports. For the ICMP protocol, you must also specify the ICMP type and code. If the security group rule has a description, you do not need to specify the description to revoke the rule.

For a default VPC, if the values you specify do not match the existing rule's values, no error is returned, and the output describes the security group rules that were not revoked.

Amazon Web Services recommends that you describe the security group to verify that the rules were removed.

Rule changes are propagated to instances within the security group as quickly as possible. However, a small delay might occur.

RevokeSecurityGroupIngressCommand

Removes the specified inbound (ingress) rules from a security group.

You can specify rules using either rule IDs or security group rule properties. If you use rule properties, the values that you specify (for example, ports) must match the existing rule's values exactly. Each rule has a protocol, from and to ports, and source (CIDR range, security group, or prefix list). For the TCP and UDP protocols, you must also specify the destination port or range of ports. For the ICMP protocol, you must also specify the ICMP type and code. If the security group rule has a description, you do not need to specify the description to revoke the rule.

For a default VPC, if the values you specify do not match the existing rule's values, no error is returned, and the output describes the security group rules that were not revoked.

For a non-default VPC, if the values you specify do not match the existing rule's values, an InvalidPermission.NotFound client error is returned, and no rules are revoked.

Amazon Web Services recommends that you describe the security group to verify that the rules were removed.

Rule changes are propagated to instances within the security group as quickly as possible. However, a small delay might occur.

RunInstancesCommand

Launches the specified number of instances using an AMI for which you have permissions.

You can specify a number of options, or leave the default options. The following rules apply:

  • If you don't specify a subnet ID, we choose a default subnet from your default VPC for you. If you don't have a default VPC, you must specify a subnet ID in the request.

  • All instances have a network interface with a primary private IPv4 address. If you don't specify this address, we choose one from the IPv4 range of your subnet.

  • Not all instance types support IPv6 addresses. For more information, see Instance types .

  • If you don't specify a security group ID, we use the default security group for the VPC. For more information, see Security groups .

  • If any of the AMIs have a product code attached for which the user has not subscribed, the request fails.

You can create a launch template , which is a resource that contains the parameters to launch an instance. When you launch an instance using RunInstances, you can specify the launch template instead of specifying the launch parameters.

To ensure faster instance launches, break up large requests into smaller batches. For example, create five separate launch requests for 100 instances each instead of one launch request for 500 instances.

RunInstances is subject to both request rate limiting and resource rate limiting. For more information, see Request throttling .

An instance is ready for you to use when it's in the running state. You can check the state of your instance using DescribeInstances. You can tag instances and EBS volumes during launch, after launch, or both. For more information, see CreateTags and Tagging your Amazon EC2 resources .

Linux instances have access to the public key of the key pair at boot. You can use this key to provide secure access to the instance. Amazon EC2 public images use this feature to provide secure access without passwords. For more information, see Key pairs .

RunScheduledInstancesCommand

Launches the specified Scheduled Instances.

Before you can launch a Scheduled Instance, you must purchase it and obtain an identifier using PurchaseScheduledInstances.

You must launch a Scheduled Instance during its scheduled time period. You can't stop or reboot a Scheduled Instance, but you can terminate it as needed. If you terminate a Scheduled Instance before the current scheduled time period ends, you can launch it again after a few minutes.

SearchLocalGatewayRoutesCommand

Searches for routes in the specified local gateway route table.

SearchTransitGatewayMulticastGroupsCommand

Searches one or more transit gateway multicast groups and returns the group membership information.

SearchTransitGatewayRoutesCommand

Searches for routes in the specified transit gateway route table.

SendDiagnosticInterruptCommand

Sends a diagnostic interrupt to the specified Amazon EC2 instance to trigger a kernel panic (on Linux instances), or a blue screen/stop error (on Windows instances). For instances based on Intel and AMD processors, the interrupt is received as a non-maskable interrupt (NMI).

In general, the operating system crashes and reboots when a kernel panic or stop error is triggered. The operating system can also be configured to perform diagnostic tasks, such as generating a memory dump file, loading a secondary kernel, or obtaining a call trace.

Before sending a diagnostic interrupt to your instance, ensure that its operating system is configured to perform the required diagnostic tasks.

For more information about configuring your operating system to generate a crash dump when a kernel panic or stop error occurs, see Send a diagnostic interrupt (for advanced users)  in the Amazon EC2 User Guide.

StartDeclarativePoliciesReportCommand

Generates an account status report. The report is generated asynchronously, and can take several hours to complete.

The report provides the current status of all attributes supported by declarative policies for the accounts within the specified scope. The scope is determined by the specified TargetId, which can represent an individual account, or all the accounts that fall under the specified organizational unit (OU) or root (the entire Amazon Web Services Organization).

The report is saved to your specified S3 bucket, using the following path structure (with the italicized placeholders representing your specific values):

s3://amzn-s3-demo-bucket/your-optional-s3-prefix/ec2_targetId_reportId_yyyyMMddThhmmZ.csv

Prerequisites for generating a report

  • The StartDeclarativePoliciesReport API can only be called by the management account or delegated administrators for the organization.

  • An S3 bucket must be available before generating the report (you can create a new one or use an existing one), it must be in the same Region where the report generation request is made, and it must have an appropriate bucket policy. For a sample S3 policy, see Sample Amazon S3 policy under .

  • Trusted access must be enabled for the service for which the declarative policy will enforce a baseline configuration. If you use the Amazon Web Services Organizations console, this is done automatically when you enable declarative policies. The API uses the following service principal to identify the EC2 service: ec2.amazonaws.com. For more information on how to enable trusted access with the Amazon Web Services CLI and Amazon Web Services SDKs, see Using Organizations with other Amazon Web Services services  in the Amazon Web Services Organizations User Guide.

  • Only one report per organization can be generated at a time. Attempting to generate a report while another is in progress will result in an error.

For more information, including the required IAM permissions to run this API, see Generating the account status report for declarative policies  in the Amazon Web Services Organizations User Guide.

StartInstancesCommand

Starts an Amazon EBS-backed instance that you've previously stopped.

Instances that use Amazon EBS volumes as their root devices can be quickly stopped and started. When an instance is stopped, the compute resources are released and you are not billed for instance usage. However, your root partition Amazon EBS volume remains and continues to persist your data, and you are charged for Amazon EBS volume usage. You can restart your instance at any time. Every time you start your instance, Amazon EC2 charges a one-minute minimum for instance usage, and thereafter charges per second for instance usage.

Before stopping an instance, make sure it is in a state from which it can be restarted. Stopping an instance does not preserve data stored in RAM.

Performing this operation on an instance that uses an instance store as its root device returns an error.

If you attempt to start a T3 instance with host tenancy and the unlimited CPU credit option, the request fails. The unlimited CPU credit option is not supported on Dedicated Hosts. Before you start the instance, either change its CPU credit option to standard, or change its tenancy to default or dedicated.

For more information, see Stop and start Amazon EC2 instances  in the Amazon EC2 User Guide.

StartNetworkInsightsAccessScopeAnalysisCommand

Starts analyzing the specified Network Access Scope.

StartNetworkInsightsAnalysisCommand

Starts analyzing the specified path. If the path is reachable, the operation returns the shortest feasible path.

StartVpcEndpointServicePrivateDnsVerificationCommand

Initiates the verification process to prove that the service provider owns the private DNS name domain for the endpoint service.

The service provider must successfully perform the verification before the consumer can use the name to access the service.

Before the service provider runs this command, they must add a record to the DNS server.

StopInstancesCommand

Stops an Amazon EBS-backed instance. For more information, see Stop and start Amazon EC2 instances  in the Amazon EC2 User Guide.

You can use the Stop action to hibernate an instance if the instance is enabled for hibernation  and it meets the hibernation prerequisites . For more information, see Hibernate your Amazon EC2 instance  in the Amazon EC2 User Guide.

We don't charge usage for a stopped instance, or data transfer fees; however, your root partition Amazon EBS volume remains and continues to persist your data, and you are charged for Amazon EBS volume usage. Every time you start your instance, Amazon EC2 charges a one-minute minimum for instance usage, and thereafter charges per second for instance usage.

You can't stop or hibernate instance store-backed instances. You can't use the Stop action to hibernate Spot Instances, but you can specify that Amazon EC2 should hibernate Spot Instances when they are interrupted. For more information, see Hibernating interrupted Spot Instances  in the Amazon EC2 User Guide.

When you stop or hibernate an instance, we shut it down. You can restart your instance at any time. Before stopping or hibernating an instance, make sure it is in a state from which it can be restarted. Stopping an instance does not preserve data stored in RAM, but hibernating an instance does preserve data stored in RAM. If an instance cannot hibernate successfully, a normal shutdown occurs.

Stopping and hibernating an instance is different to rebooting or terminating it. For example, when you stop or hibernate an instance, the root device and any other devices attached to the instance persist. When you terminate an instance, the root device and any other devices attached during the instance launch are automatically deleted. For more information about the differences between rebooting, stopping, hibernating, and terminating instances, see Instance lifecycle  in the Amazon EC2 User Guide.

When you stop an instance, we attempt to shut it down forcibly after a short while. If your instance appears stuck in the stopping state after a period of time, there may be an issue with the underlying host computer. For more information, see Troubleshoot stopping your instance  in the Amazon EC2 User Guide.

TerminateClientVpnConnectionsCommand

Terminates active Client VPN endpoint connections. This action can be used to terminate a specific client connection, or up to five connections established by a specific user.

TerminateInstancesCommand

Shuts down the specified instances. This operation is idempotent; if you terminate an instance more than once, each call succeeds.

If you specify multiple instances and the request fails (for example, because of a single incorrect instance ID), none of the instances are terminated.

If you terminate multiple instances across multiple Availability Zones, and one or more of the specified instances are enabled for termination protection, the request fails with the following results:

  • The specified instances that are in the same Availability Zone as the protected instance are not terminated.

  • The specified instances that are in different Availability Zones, where no other specified instances are protected, are successfully terminated.

For example, say you have the following instances:

  • Instance A: us-east-1a; Not protected

  • Instance B: us-east-1a; Not protected

  • Instance C: us-east-1b; Protected

  • Instance D: us-east-1b; not protected

If you attempt to terminate all of these instances in the same request, the request reports failure with the following results:

  • Instance A and Instance B are successfully terminated because none of the specified instances in us-east-1a are enabled for termination protection.

  • Instance C and Instance D fail to terminate because at least one of the specified instances in us-east-1b (Instance C) is enabled for termination protection.

Terminated instances remain visible after termination (for approximately one hour).

By default, Amazon EC2 deletes all EBS volumes that were attached when the instance launched. Volumes attached after instance launch continue running.

You can stop, start, and terminate EBS-backed instances. You can only terminate instance store-backed instances. What happens to an instance differs if you stop it or terminate it. For example, when you stop an instance, the root device and any other devices attached to the instance persist. When you terminate an instance, any attached EBS volumes with the DeleteOnTermination block device mapping parameter set to true are automatically deleted. For more information about the differences between stopping and terminating instances, see Instance lifecycle  in the Amazon EC2 User Guide.

For more information about troubleshooting, see Troubleshooting terminating your instance  in the Amazon EC2 User Guide.

UnassignIpv6AddressesCommand

Unassigns the specified IPv6 addresses or Prefix Delegation prefixes from a network interface.

UnassignPrivateIpAddressesCommand

Unassigns the specified secondary private IP addresses or IPv4 Prefix Delegation prefixes from a network interface.

UnassignPrivateNatGatewayAddressCommand

Unassigns secondary private IPv4 addresses from a private NAT gateway. You cannot unassign your primary private IP. For more information, see Edit secondary IP address associations  in the Amazon VPC User Guide.

While unassigning is in progress, you cannot assign/unassign additional IP addresses while the connections are being drained. You are, however, allowed to delete the NAT gateway.

A private IP address will only be released at the end of MaxDrainDurationSeconds. The private IP addresses stay associated and support the existing connections, but do not support any new connections (new connections are distributed across the remaining assigned private IP address). After the existing connections drain out, the private IP addresses are released.

UnlockSnapshotCommand

Unlocks a snapshot that is locked in governance mode or that is locked in compliance mode but still in the cooling-off period. You can't unlock a snapshot that is locked in compliance mode after the cooling-off period has expired.

UnmonitorInstancesCommand

Disables detailed monitoring for a running instance. For more information, see Monitoring your instances and volumes  in the Amazon EC2 User Guide.

UpdateSecurityGroupRuleDescriptionsEgressCommand

Updates the description of an egress (outbound) security group rule. You can replace an existing description, or add a description to a rule that did not have one previously. You can remove a description for a security group rule by omitting the description parameter in the request.

UpdateSecurityGroupRuleDescriptionsIngressCommand

Updates the description of an ingress (inbound) security group rule. You can replace an existing description, or add a description to a rule that did not have one previously. You can remove a description for a security group rule by omitting the description parameter in the request.

WithdrawByoipCidrCommand

Stops advertising an address range that is provisioned as an address pool.

You can perform this operation at most once every 10 seconds, even if you specify different address ranges each time.

It can take a few minutes before traffic to the specified addresses stops routing to Amazon Web Services because of BGP propagation delays.
