/**
 * Client for accessing Application Auto Scaling. All service calls made using this client are blocking, and will not
 * return until the service call completes.
 * 

*

* Application Auto Scaling is a general purpose Auto Scaling service for supported elastic AWS resources. With * Application Auto Scaling, you can automatically scale your AWS resources, with an experience similar to that of Auto * Scaling. *

*

* Application Auto Scaling supports scaling the following AWS resources: *

*
    *
  • *

    * Amazon ECS services *

    *
  • *
  • *

    * Amazon EC2 Spot fleet instances *

    *
  • *
*

* You can use Application Auto Scaling to accomplish the following tasks: *

*
    *
  • *

    * Define scaling policies for automatically adjusting your AWS resources *

    *
  • *
  • *

    * Scale your resources in response to CloudWatch alarms *

    *
  • *
  • *

    * View history of your scaling events *

    *
  • *
*

* Application Auto Scaling is available in the following regions: *

*
    *
  • *

    * us-east-1 *

    *
  • *
  • *

    * us-west-1 *

    *
