How can I resize EC2 instances that are built on the Nitro System?

Resolution

Use the AWSPremiumSupport-ResizeNitroInstance runbook to resize your Amazon EC2 instances that are built on the Nitro System. Access to the AWSPremiumSupport-ResizeNitroInstance runbook requires a Business Support+, Enterprise Support, or Unified Operations plan. For more information, see AWS Support.

Prerequisites: Before you start the runbook, make sure that your AWS Identify and Access Management (IAM) user or role has the required permissions. For more information, see the Required IAM permissions section of AWSPremiumSupport-ResizeNitroInstance.

The runbook provides two ways to specify the instance type that you want to change to:

• TargetInstanceTypeFromParameter: Use for simple automations that target a single instance.
• TargetInstanceTypeFromTagValue: Use to run automations at scale to change the instance type of several instances.

If you don't specify a value for either parameter, then the automation fails.

To run the AWS Systems Manager automation runbook, complete the following steps:

1. Open the Systems Manager console.
2. In the navigation pane, choose Documents.
3. In the search bar, enter AWSPremiumSupport-ResizeNitroInstance.
4. Choose AWSPremiumSupport-ResizeNitroInstance.
5. Choose Execute automation.
6. Choose Execute.
   Note: For a list of the steps that the runbook performs, see the Document steps section of AWSPremiumSupport-ResizeNitroInstance.
7. After the automation completes, review the Outputs section to see detailed results.
