Amazon EC2 Auto Scaling now lets you configure your Auto Scaling group with multiple launch templates when you use a MixedInstancesPolicy and specify multiple instance types. After EC2 Auto Scaling released support for multiple instance types within a single Auto Scaling group, customers have been looking for ways to launch different instance types using different Amazon Machine Images (AMIs) so that instances with incompatible CPU architectures can exist in the same Auto Scaling group. With this enhancement you can now specify a launch template alongside the instance type in the overrides of your MixedInstancesPolicy, and that launch template will be used whenever launching instances of its corresponding instance type.
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. This feature is available in all commercial and AWS GovCloud (US) Regions where Amazon EC2 Auto Scaling is available. For more information, visit the Amazon EC2 Auto Scaling documentation page.
