Amazon EC2 Auto Scaling now supports Instance Refresh in CloudFormation

calendar_today July 29, 2026 person aws@amazon.com domain amazon-q

Amazon EC2 Auto Scaling now supports Instance Refresh as a new AWS CloudFormation update policy. When you configure the new AutoScalingInstanceRefresh update policy and update properties that require instance replacement, CloudFormation automatically triggers an Instance Refresh. With this integration, you can now access Instance Refresh capabilities including replace root volume for in-place updates, launch-before-terminate, alarm-based monitoring, and checkpoints with bake time for controlled rollouts.
