Description

This check verifies if an Amazon EC2 Auto Scaling group is established using an EC2 launch template. The check does not pass if the Auto Scaling group is created without a launch template, or if a launch template is absent in a mixed instances policy.

An EC2 Auto Scaling group can be formed using either an EC2 launch template or a launch configuration. Opting for a launch template when creating an Auto Scaling group guarantees access to the latest features and enhancements.

Remediation

Additionally, for details on substituting a launch configuration with a launch template, see Replace a launch configuration with a launch template in the Amazon EC2 User Guide for Windows Instances.
