AWS::AutoScaling::AutoScalingGroup LaunchTemplate

LaunchTemplate is a property of the AWS::AutoScaling::AutoScalingGroup MixedInstancesPolicy property type that describes a launch template and overrides. The overrides are used to override the instance type specified by the launch template with multiple instance types that can be used to launch On-Demand Instances and Spot Instances. The overrides also support attribute-based instance type selection, so that you can specify a set of requirements for the types of instances that can be launched.
