EC2 Fast Launch prerequisites for Windows - Amazon Elastic Compute Cloud

EC2 Fast Launch prerequisites for Windows

Before you set up EC2 Fast Launch, verify that you've met the following prerequisites that are required to create snapshots for the AMIs in your AWS account:

  • If you don't use a launch template to configure your settings, ensure that a default VPC is configured for the Region in which you use EC2 Fast Launch.

    If you accidentally delete your default VPC in the Region where you plan to configure EC2 Fast Launch, you can create a new default VPC in that Region. To learn more, see Create a default VPC in the Amazon VPC User Guide.

  • To specify a non-default VPC, you must use a launch template when you configure Windows fast launch. For more information, see Use a launch template when you set up EC2 Fast Launch.

  • If your account includes a policy that enforces IMDSv2 for Amazon EC2 instances, you must create a launch template that specifies the metadata configuration to enforce IMDSv2.

  • Private EC2 Fast Launch AMIs must support user data script execution.

  • To configure EC2 Fast Launch for an AMI, you must create the AMI using Sysprep with the shutdown option. The EC2 Fast Launch feature doesn't currently support AMIs that were created from a running instance.

    To create an AMI using Sysprep, see Create an Amazon EC2 AMI using Windows Sysprep.

  • To enable EC2 Fast Launch for an encrypted AMI that uses a customer managed key for encryption, you must grant the service-linked role for EC2 Fast Launch permission to use the CMK. For more information, see Access to customer managed keys.

  • The default quota for Max parallel launches across all AMIs in an AWS account is 40 per Region. You can request a Service Quotas increase for your account, as follows.

    1. Open the Service Quotas console at https://console.aws.amazon.com/servicequotas/.

    2. In the navigation pane, choose AWS services.

    3. In the search bar, enter EC2 Fast Launch, and select the result.

    4. Select the link for Parallel instance launches to open the service quota detail page.

    5. Choose Request increase at account level.

    For more information, see Requesting a quota increase in the Service Quotas User Guide.
