// With Application Auto Scaling, you can automatically scale your AWS resources.
// The experience similar to that of Auto Scaling (https://aws.amazon.com/autoscaling/).
// You can use Application Auto Scaling to accomplish the following tasks:
//
//    * Define scaling policies to automatically scale your AWS resources
//
//    * Scale your resources in response to CloudWatch alarms
//
//    * View the history of your scaling events
//
// Application Auto Scaling can scale the following AWS resources:
//
//    * Amazon ECS services. For more information, see Service Auto Scaling
//    (http://docs.aws.amazon.com/AmazonECS/latest/developerguide/service-auto-scaling.html)
//    in the Amazon EC2 Container Service Developer Guide.
//
//    * Amazon EC2 Spot fleets. For more information, see Automatic Scaling
//    for Spot Fleet (http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/fleet-auto-scaling.html)
//    in the Amazon EC2 User Guide.
//
//    * Amazon EMR clusters. For more information, see Using Automatic Scaling
//    in Amazon EMR (http://docs.aws.amazon.com/ElasticMapReduce/latest/ManagementGuide/emr-automatic-scaling.html)
//    in the Amazon EMR Management Guide.
//
//    * AppStream 2.0 fleets. For more information, see Autoscaling Amazon AppStream
//    2.0 Resources (http://docs.aws.amazon.com/appstream2/latest/developerguide/autoscaling.html)
//    in the Amazon AppStream 2.0 Developer Guide.
//
// For a list of supported regions, see AWS Regions and Endpoints: Application
// Auto Scaling (http://docs.aws.amazon.com/general/latest/gr/rande.html#as-app_region)
// in the AWS General Reference.
// The service client's operations are safe to be used concurrently.
// It is not safe to mutate any of the client's properties though.
