Amazon EC2 Auto Scaling supports final validation time for instance refresh
Starting today, you can utilize a final validation period while using EC2 Auto Scaling instance refresh. This new feature gives you time to conduct necessary validation or testing, ensuring the successful deployment of new EC2 instances to your Auto Scaling group before an instance refresh is marked successful.
With an instance refresh, you can update EC2 instances in your Auto Scaling groups either all at once or incrementally using instance refresh checkpoints. These checkpoints enable you to validate the health of replaced instances at different stages. The new final validation time provides extra time to monitor the health of all updated instances, address any last-minute issues, and confirm a successful deployment before an instance refresh is completed. During this period, you can also take advantage of manual or automatic rollbacks as needed to revert any changes.
This feature is available in all AWS commercial regions, and the AWS GovCloud (US) Regions. To learn more, see the EC2 Auto Scaling instance refresh documentation.
