/**
* Interface 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.
*
*
* 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
*
*
* -
*
* us-west-2
*
*
* -
*
* ap-southeast-1
*
*
* -
*
* ap-southeast-2
*
*
* -
*
* ap-northeast-1
*
*
* -
*
* eu-central-1
*
*
* -
*
* eu-west-1
