A CloudFormation `AWS::ApplicationAutoScaling::ScalingPolicy`.

The AWS::ApplicationAutoScaling::ScalingPolicy resource defines a scaling policy that Application Auto Scaling uses to adjust the capacity of a scalable target.

For more information, see PutScalingPolicy in the Application Auto Scaling API Reference . For more information about Application Auto Scaling scaling policies, see Target tracking scaling policies and Step scaling policies in the Application Auto Scaling User Guide .
