AWS managed policies for AWS Database Migration Service

AWS managed policy: AmazonDMSVPCManagementRole

This policy is attached to the dms-vpc-role role, which allows AWS DMS to perform actions on your behalf.

This policy grants contributor permissions that allow AWS DMS to manage network resources.

Permissions details

This policy includes the following operations:

  • ec2:CreateNetworkInterface – AWS DMS needs this permission to create network interfaces. These interfaces are essential for the AWS DMS replication instance to connect to the source and target databases.

  • ec2:DeleteNetworkInterface – AWS DMS needs this permission to clean up network interfaces that it created once they are no longer needed. This helps in resource management and avoiding unnecessary costs.

  • ec2:DescribeAvailabilityZones – This permission allows AWS DMS to retrieve information about the availability zones in a region. AWS DMS uses this information to ensure that it provisions resources in the correct zones for redundancy and availability.

  • ec2:DescribeDhcpOptions – AWS DMS retrieves the DHCP options set details for the specified VPC. This information is required to configure the networking correctly for the replication instances.

  • ec2:DescribeInternetGateways – AWS DMS may require this permission to understand the internet gateways configured in the VPC. This information is crucial if the replication instance or databases need internet access.

  • ec2:DescribeNetworkInterfaces – AWS DMS retrieves information about existing network interfaces within the VPC. This information is necessary for AWS DMS to configure the network interfaces correctly and ensure proper network connectivity for the migration process.

  • ec2:DescribeSecurityGroups – Security groups control the inbound and outbound traffic to instances and resources. AWS DMS needs to describe security groups to correctly configure network interfaces and ensure proper communication between the replication instance and the databases.

  • ec2:DescribeSubnets – This permission allows AWS DMS to list the subnets in a VPC. AWS DMS uses this information to launch replication instances in the appropriate subnets, ensuring they have the necessary network connectivity.

  • ec2:DescribeVpcs – Describing VPCs is essential for AWS DMS to understand the network environment where the replication instance and databases reside. This includes knowing the CIDR blocks and other VPC-specific configurations.

  • ec2:ModifyNetworkInterfaceAttribute – This permission is required for AWS DMS to modify attributes of the network interfaces it manages. This could include adjusting settings to ensure connectivity and security.
