};Remarks
A mixed instances policy contains information that Amazon EC2 Auto Scaling can use to launch instances and help optimize your costs. For more information, see Auto Scaling groups with multiple instance types and purchase options in the Amazon EC2 Auto Scaling User Guide .
You can create a mixed instances policy for new and existing Auto Scaling groups. You must use a launch template to configure the policy. You cannot use a launch configuration.
There are key differences between Spot Instances and On-Demand Instances:
When a Spot Instance is terminated, Amazon EC2 Auto Scaling group attempts to launch a replacement instance to maintain the desired capacity for the group.
MixedInstancesPolicy is a property of the AWS::AutoScaling::AutoScalingGroup resource.
