Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

EC2 Fast Launch prerequisites

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 Amazon Web Services 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.

    Note

    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 Use EC2 launch agents to create an AMI with Windows Sysprep.

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

    1. Sign in to the Amazon Web Services Management Console and open the Service Quotas console at https://console.amazonaws.cn/servicequotas/.

    2. In the navigation pane, choose Amazon Web Services.

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

    4. Select the link for Parallel instance launches. This takes you to the Parallel instance launches service quota detail page.

    5. Choose Request quota increase.

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