Interface ApplicationAutoScalingAsyncClient

All Superinterfaces:

AutoCloseable

@Generated("software.amazon.awssdk:codegen")
public interface ApplicationAutoScalingAsyncClient
extends AutoCloseable

Service client for accessing null asynchronously. This can be created using the static builder() method.

With Application Auto Scaling, you can automatically scale your AWS resources. The experience similar to that of Auto Scaling. You can use Application Auto Scaling to accomplish the following tasks:

• Define scaling policies to automatically scale your AWS resources

• Scale your resources in response to CloudWatch alarms

• View the history of your scaling events

Application Auto Scaling can scale the following AWS resources:

• Amazon ECS services. For more information, see Service Auto Scaling in the Amazon EC2 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 Auto Scaling for DynamoDB in the Amazon DynamoDB Developer Guide.

For a list of supported regions, see AWS Regions and Endpoints: Application Auto Scaling in the AWS General Reference.

Method Detail

create

static ApplicationAutoScalingAsyncClient create()

deleteScalingPolicy

default CompletableFuture<DeleteScalingPolicyResponse> deleteScalingPolicy(DeleteScalingPolicyRequest deleteScalingPolicyRequest)

Deletes the specified Application Auto Scaling scaling policy.

Deleting a policy deletes the underlying alarm action, but does not delete the CloudWatch alarm associated with the scaling policy, even if it no longer has an associated action.

To create a scaling policy or update an existing one, see PutScalingPolicy.

Parameters:

deleteScalingPolicyRequest -

Returns:

A Java Future containing the result of the DeleteScalingPolicy operation returned by the service.
The CompletableFuture returned by this method can be completed exceptionally with the following exceptions.

• ValidationException An exception was thrown for a validation issue. Review the available parameters for the API request.
• ObjectNotFoundException The specified object could not be found. For any Put or Register API operation, which depends on the existence of a scalable target, this exception is thrown if the scalable target with the specified service namespace, resource ID, and scalable dimension does not exist. For any Delete or Deregister API operation, this exception is thrown if the resource that is to be deleted or deregistered cannot be found.
• ConcurrentUpdateException Concurrent updates caused an exception, for example, if you request an update to an Application Auto Scaling resource that already has a pending update.
• InternalServiceException The service encountered an internal error.
• SdkBaseException Base class for all exceptions that can be thrown by the SDK (both service and client). Can be used for catch all scenarios.
• SdkClientException If any client side error occurs such as an IO related failure, failure to get credentials, etc
• ApplicationAutoScalingException Base class for all service exceptions. Unknown exceptions will be thrown as an instance of this

putScalingPolicy

default CompletableFuture<PutScalingPolicyResponse> putScalingPolicy(PutScalingPolicyRequest putScalingPolicyRequest)

Creates or updates a policy for an Application Auto Scaling scalable target.

Each scalable target is identified by a service namespace, resource ID, and scalable dimension. A scaling policy applies to the scalable target identified by those three attributes. You cannot create a scaling policy without first registering a scalable target using RegisterScalableTarget.

To update a policy, specify its policy name and the parameters that you want to change. Any parameters that you don't specify are not changed by this update request.

You can view the scaling policies for a service namespace using DescribeScalingPolicies. If you are no longer using a scaling policy, you can delete it using DeleteScalingPolicy.

Parameters:

putScalingPolicyRequest -

Returns:

A Java Future containing the result of the PutScalingPolicy operation returned by the service.
The CompletableFuture returned by this method can be completed exceptionally with the following exceptions.

• ValidationException An exception was thrown for a validation issue. Review the available parameters for the API request.

registerScalableTarget

default CompletableFuture<RegisterScalableTargetResponse> registerScalableTarget(RegisterScalableTargetRequest registerScalableTargetRequest)

Registers or updates a scalable target. A scalable target is a resource that Application Auto Scaling can scale out or scale in. After you have registered a scalable target, you can use this operation to update the minimum and maximum values for your scalable dimension.

After you register a scalable target, you can create and apply scaling policies using PutScalingPolicy. You can view the scaling policies for a service namespace using DescribeScalableTargets. If you are no longer using a scalable target, you can deregister it using DeregisterScalableTarget.

Parameters:

registerScalableTargetRequest -

Returns:

A Java Future containing the result of the RegisterScalableTarget operation returned by the service.
