/**
* Interface for accessing Application Auto Scaling.
*
* Note: Do not directly implement this interface, new methods are added to it regularly. Extend from
* {@link com.amazonaws.services.applicationautoscaling.AbstractAWSApplicationAutoScaling} instead.
*
*
*
* With Application Auto Scaling, you can configure automatic scaling for your scalable resources. You can use
* Application Auto Scaling to accomplish the following tasks:
*
*
* -
*
* Define scaling policies to automatically scale your AWS or custom resources
*
*
* -
*
* Scale your resources in response to CloudWatch alarms
*
*
* -
*
* Schedule one-time or recurring scaling actions
*
*
* -
*
* View the history of your scaling events
*
*
*
*
* Application Auto Scaling can scale the following resources:
*
*
* -
*
* Amazon ECS services. For more information, see Service Auto Scaling
* in the Amazon Elastic Container Service Developer Guide.
*
*
* -
*
* Amazon EC2 Spot fleets. For more information, see Automatic Scaling for Spot
* Fleet in the Amazon EC2 User Guide.
*
*
* -
*
* Amazon EMR clusters. For more information, see Using Automatic
* Scaling in Amazon EMR in the Amazon EMR Management Guide.
*
*
* -
*
* AppStream 2.0 fleets. For more information, see Fleet Auto Scaling for Amazon
* AppStream 2.0 in the Amazon AppStream 2.0 Developer Guide.
*
*
* -
*
* Provisioned read and write capacity for Amazon DynamoDB tables and global secondary indexes. For more information,
* see Managing Throughput
* Capacity Automatically with DynamoDB Auto Scaling in the Amazon DynamoDB Developer Guide.
*
*
* -
*
* Amazon Aurora Replicas. For more information, see Using Amazon
* Aurora Auto Scaling with Aurora Replicas.
*
*
* -
*
* Amazon SageMaker endpoint variants. For more information, see Automatically Scaling Amazon
* SageMaker Models.
*
*
* -
*
* Custom resources provided by your own applications or services. More information is available in our GitHub repository.
*

* (200% of 10 = 20) and scales out to 30.
