Amazon EC2 Auto Scaling now supports Instance Refresh within Auto Scaling Groups
Amazon EC2 Auto Scaling now lets you automatically update the instances in your Auto Scaling Groups (ASG) to release new application versions or make infrastructure changes. Traditionally, customers had to write custom scripts and build systems to update ASG configurations with new AMIs. With the new Instance Refresh feature, customers can now trigger configuration updates such as moving to new AMIs and changing instance types. You can roll out these updates to the ASG by replacing instances all at once or gradually.

Amazon EC2 Auto Scaling helps you maintain application availability and allows you to automatically add or remove EC2 instances according to conditions you define. You can use the fleet management features to maintain the health and availability of your fleet. You can also use the dynamic and predictive scaling policies to add or remove EC2 instances. EC2 Auto Scaling is available in all AWS commercial Regions and AWS GovCloud (US Regions).
