public static interface CfnAutoScalingGroup.MixedInstancesPolicyProperty

`MixedInstancesPolicy` is a property of the [AWS::AutoScaling::AutoScalingGroup](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-as-group.html) resource. It allows you to configure a group that diversifies across On-Demand Instances and Spot Instances of multiple instance types. For more information, see [Auto Scaling groups with multiple instance types and purchase options](https://docs.aws.amazon.com/autoscaling/ec2/userguide/ec2-auto-scaling-mixed-instances-groups.html) in the *Amazon EC2 Auto Scaling User Guide* .

You can create a mixed instances policy for a new Auto Scaling group, or you can create it for an existing group by updating the group to specify MixedInstancesPolicy as the top-level property instead of a launch template or launch configuration. If you specify a MixedInstancesPolicy , you must specify a launch template as a property of the policy. You cannot specify a launch configuration for the policy.

Example:

 // The code below shows an example of how to instantiate this type.
 // The values are placeholders you should change.
 import software.amazon.awscdk.services.autoscaling.*;
