/**
* Client for accessing Application Auto Scaling asynchronously. Each asynchronous method will return a Java Future
* object representing the asynchronous operation; overloads which accept an {@code AsyncHandler} can be used to receive
* notification when an asynchronous operation completes.
* <p>
* <p>
* With Application Auto Scaling, you can automatically scale your AWS resources. The experience similar to that of <a
* href="https://aws.amazon.com/autoscaling/">Auto Scaling</a>. You can use Application Auto Scaling to accomplish the
* following tasks:
* </p>
* <ul>
* <li>
* <p>
* Define scaling policies to automatically scale your AWS resources
* </p>
* </li>
* <li>
* <p>
* Scale your resources in response to CloudWatch alarms
* </p>
* </li>
* <li>
* <p>
* View the history of your scaling events
* </p>
* </li>
* </ul>
* <p>
* Application Auto Scaling can scale the following AWS resources:
* </p>
* <ul>
* <li>
* <p>
* Amazon ECS services. For more information, see <a
