# Create a Fleet in Amazon WorkSpaces Applications Set up and create a fleet from which user applications are launched and streamed. **Note** To create an Always-On or On-Demand fleet, you must have an image that has applications installed to create an Always-On or On-Demand fleet that your users can stream from. To create an image, see [Tutorial: Create a Custom WorkSpaces Applications Image by Using the WorkSpaces Applications Console](tutorial-image-builder.md). To create an Elastic fleet, you must have applications associated to app blocks. To create applications and app blocks for an Elastic fleet, see [Applications Manager](app-blocks-applications.md). **To set up and create a fleet** 1. Open the WorkSpaces Applications console at [https://console.aws.amazon.com/appstream2/home](https://console.aws.amazon.com/appstream2/home). 1. Choose **Get Started** if you are new to the console, or **Fleets** from the left navigation pane. Choose **Create Fleet**. 1. For **Step 1: Select fleet type**, review the details of the fleet types, choose the type of fleet to create based on your use case, and select **Next**. **Note** The fleet type determines its immediate availability and how you pay for it. For more information, see [WorkSpaces Applications Fleet Types](fleet-type.md). 1. If you chose to create an Always-On or On-Demand fleet, for **Step 2: Choose an Image**, choose an image that meets your needs and then choose **Next**. 1. If you chose to create an Elastic fleet, for **Step 2: Assign applications**, choose the applications that users can launch from this fleet. 1. For **Step 3: Configure fleet**, enter the following **details**: + For **Name**, enter a unique name identifier for the fleet. Special characters aren't allowed. + For **Display Name**, enter a name to display for the fleet (maximum of 100 characters). Special characters aren't allowed. + For **Description**, enter a description for the fleet (maximum of 256 characters). + For **Choose instance type**, choose the instance type that meets the performance requirements of your applications. All streaming instances in your fleet launch with the instance type that you select. For more information, see [WorkSpaces Applications Instance Families](instance-types.md). + You can use stream.\$1 instance types for images with `type = "native"`. To use any of the following instance type you must [Import Image](import-image.md) and create an image with `type = "custom"`. + GeneralPurpose.\$1 + MemoryOptimized.\$1 + ComputeOptimized.\$1 + Accelerated.\$1 + Configure **storage** volumes for Always-On or On-Demand fleet instances. By default, the storage volume matches your image volume size, with a service default of 200 GB included in the hourly instance rate. You can customize your storage capacity from 200 GB up to 500 GB based on your requirements. **Note** Note: Storage volume size cannot be set below the image volume size. Storage capacity can be increased up to 500 GB, with additional charges applying to any storage beyond the included 200 GB. These charges apply to fleet instances regardless of their running state (both running and stopped instances). + For Elastic fleets, for **Choose platform type**, choose the operating system that matches the requirements of your users’ applications. + For **Maximum session duration in minutes**, choose the maximum amount of time that a streaming session can remain active. If users are still connected to a streaming instance five minutes before this limit is reached, they are prompted to save any open documents before being disconnected. After this time elapses, the instance is terminated and replaced by a new instance. The maximum session duration that you can set in the WorkSpaces Applications console is 5760 minutes (96 hours). The maximum session duration that you can set using the WorkSpaces Applications API and CLI is 432000 seconds (120 hours). + For **Disconnect timeout in minutes**, choose the amount of time that a streaming session remains active after users disconnect. If users try to reconnect to the streaming session after a disconnection or network interruption within this time interval, they are connected to their previous session. Otherwise, they are connected to a new session with a new streaming instance. If you associate a stack with a fleet for which a redirect URL is specified, after users’ streaming sessions end, the users are redirected to that URL. If a user ends the session by choosing **End Session** or **Logout** on the WorkSpaces Applications toolbar, the disconnect timeout does not apply. Instead, the user is prompted to save any open documents, and then immediately disconnected from the streaming instance. The instance the user was using is then terminated. + For **Idle disconnect timeout in minutes**, choose the amount of time that users can be idle (inactive) before they are disconnected from their streaming session and the **Disconnect timeout in minutes** time interval begins. Users are notified before they are disconnected due to inactivity. If they try to reconnect to the streaming session before the time interval specified in **Disconnect timeout in minutes** has elapsed, they are connected to their previous session. Otherwise, they are connected to a new session with a new streaming instance. Setting this value to 0 disables it. When this value is disabled, users are not disconnected due to inactivity. **Note** Users are considered idle when they stop providing keyboard or mouse input during their streaming session. For domain-joined fleets, the countdown for the idle disconnect timeout doesn't begin until users log in with their Active Directory domain password or with a smart card. File uploads and downloads, audio in, audio out, and pixels changing do not qualify as user activity. If users continue to be idle after the time interval in **Idle disconnect timeout in minutes** elapses, they are disconnected. + For Elastic fleets, for **Max concurrent sessions**, specify the maximum number of concurrent sessions this fleet should have. **Note** If you get an error message that says “The maximum number of concurrent sessions for your account was exceeded," you can submit a limit increase, through the Service Quotas console at [https://console.aws.amazon.com/servicequotas/](https://console.aws.amazon.com/servicequotas/). For more information, see [Requesting a quota increase](https://docs.aws.amazon.com/servicequotas/latest/userguide/request-quota-increase.html) in the *Service Quotas User Guide*. + **Multiple user sessions** — Choose this option if you want to provision multiple user sessions on a single instance. By default, every unique user session is served by an instance (single-session). **Note** Multi-session is available only on Always-on and On-demand fleets powered by a Windows operating system. Multi-session is not available on Elastic fleets or the Linux operating system. Only base images and managed image updates released on or after May 15, 2023 support multi-session fleets. For more details, see [WorkSpaces Applications Base Image and Managed Image Update Release Notes](base-image-version-history.md). + **Maximum sessions per instance** — Maximum number of user sessions on an instance. You must choose this value based on your end users' application performance needs. You can also adjust the maximum sessions per instance for a fleet after it is provisioned. In that case, the existing user sessions and instances will not be impacted, but the fleet will become consistent with the new value of maximum sessions per instance. The value must be between 2 and 50. Before setting this value for your fleet, see [Multi-Session Recommendations](multi-session-recs.md). + For Always-On and On-Demand fleets, for **Minimum capacity**, choose a minimum number of instances (for single-session fleets) or user sessions (for multi-session fleets) for your fleet based on the minimum number of expected concurrent users. + For Always-On and On-Demand fleets, for **Maximum capacity**, choose a maximum number of instances (for single-session fleets) or user sessions (for multi-session fleets) for your fleet based on the maximum number of expected concurrent users. **Note** For multi-session, you must specify the capacity based on the number of user sessions. The service will calculate the required number of instances to be launched, based on your fleet configuration and the value of maximum sessions per instance. + For **Stream view**, choose the WorkSpaces Applications view that is displayed to your users during their streaming sessions. Choose **Application** to display only the windows of applications opened by users. Choose **Desktop** to display the standard desktop that is provided by the operating system. **Note** By default, WorkSpaces Applications displays only the windows of applications opened by users during their streaming sessions. To enable **Desktop **view for your users, configure your fleet to use an WorkSpaces Applications image that uses a version of the WorkSpaces Applications agent released on or after February 19, 2020. + For **Scaling details (Advanced)**, specify the scaling policies that WorkSpaces Applications uses to increase and decrease the capacity of your fleet. Note that the size of your fleet is limited by the minimum and maximum capacity that you specified. For more information, see [Fleet Auto Scaling for Amazon WorkSpaces Applications](autoscaling.md). + For **IAM role (Advanced)**, when you apply an IAM role from your account to an WorkSpaces Applications fleet instance, you can make AWS API requests from the fleet instance without manually managing AWS credentials. To apply an IAM role, do either of the following: + To use an existing IAM role in your AWS account, choose the role that you want to use from the **IAM role** list. The role must be accessible from the fleet instance. For more information, see [Configuring an Existing IAM Role to Use With WorkSpaces Applications Streaming Instances](configuring-existing-iam-role-to-use-with-streaming-instances.md). + To create a new IAM role, choose **Create new IAM role** and follow the steps in [How to Create an IAM Role to Use With WorkSpaces Applications Streaming Instances](how-to-create-iam-role-to-use-with-streaming-instances.md). + For Elastic fleets, for **USB Redirection (advanced)**, you can specify up to 10 strings that specify what types of USB devices that are attached to the local device can be redirected into the streaming session when using the Windows native client. For more information, see [Qualify USB Devices for Use with Streaming Applications](qualify-usb-devices.md). 1. Choose **Next**. 1. If you chose to create an Always-On or On-Demand fleet, for **Step 3: Choose an Image**, choose an image that meets your needs and then choose **Next**. 1. If you chose to create an Elastic fleet, for **Step 3: Assign applications**, choose the applications that users can launch from this fleet. 1. For **Step 4: Configure Network**, do the following: + To add internet access for fleet instances in a VPC with a public subnet, choose **Default Internet Access**. If you are providing internet access by using a NAT gateway, leave **Default Internet Access** unselected. For more information, see [Internet Access](internet-access.md). **Note** Your VPC must provide access to Amazon Simple Storage Service (S3) if you enable features that rely on saving to an S3 bucket. For more information, see [Using Amazon S3 VPC Endpoints for WorkSpaces Applications Features](managing-network-vpce-iam-policy.md). + For **VPC** and **Subnet 1**, choose a VPC and at least one subnet that has access to the network resources that your application needs. For increased fault tolerance, we recommend that you choose two subnets in different Availability Zones. For more information, see [Configure a VPC with Private Subnets and a NAT Gateway](managing-network-internet-NAT-gateway.md). **Note** Elastic fleets require that you specify at least two subnets that are in different availability zones. If you don't have your own VPC and subnet, you can use the [default VPC](default-vpc-with-public-subnet.md) or create your own. To create your own, choose the **Create a new VPC** and **Create new subnet** links to create them. Choosing these links opens the Amazon VPC console. After you create your VPC and subnets, return to the WorkSpaces Applications console and choose the refresh icon to the left of the **Create a new VPC** and **Create new subnet** links to display them in the list. For more information, see [Configure a VPC for WorkSpaces Applications](appstream-vpc.md). + For **Security group(s)**, choose up to five security groups to associate with this fleet. If you don't have your own security group and you don't want to use the default security group, choose the **Create new security group** link to create one. After you create your subnets in the Amazon VPC console, return to the WorkSpaces Applications console and choose the refresh icon to the left of the **Create new security group** link to display them in the list. For more information, see [Security Groups in Amazon WorkSpaces Applications](managing-network-security-groups.md). + For Always-On and On-Demand fleets, for **Active Directory Domain (Optional)**, choose the Active Directory and organizational unit (OU) for your streaming instance computer objects. Ensure that the network access settings you selected enable DNS resolvability and communication with your directory. For more information, see [Using Active Directory with WorkSpaces Applications](active-directory.md). 1. Choose **Next**. 1. For **Step 5: Review**, confirm the details for the fleet. To change the configuration for any section, choose **Edit **and make the needed changes. After you finish reviewing the configuration details, choose **Create**. 1. In the pricing acknowledgement dialog box, select the acknowledgement check box, and choose **Create**. **Note** If an error message notifies you that you don't have sufficient limits (quotas) to create the fleet, submit a limit increase request through the Service Quotas console at [https://console.aws.amazon.com/servicequotas/](https://console.aws.amazon.com/servicequotas/). For more information, see [Requesting a quota increase](https://docs.aws.amazon.com/servicequotas/latest/userguide/request-quota-increase.html) in the *Service Quotas User Guide*. 1. While your fleet is being created, the status of your fleets displays as **Starting** in the **Fleets** list. Choose the **Refresh** icon periodically to update the fleet status until the status is **Running**. You cannot associate the fleet with a stack and use it for streaming sessions until the status of the fleet is **Running**.
