* <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>

* After you register a scalable target, you can create and apply scaling policies using <a>PutScalingPolicy</a>.

* @throws ValidationException
* An exception was thrown for a validation issue. Review the available parameters for the API request.
* @throws LimitExceededException
* Your account exceeded a limit. This exception is thrown when a per-account resource limit is exceeded.
