Class AWSApplicationAutoScalingAsyncClient

  • All Implemented Interfaces:
    AWSApplicationAutoScaling, AWSApplicationAutoScalingAsync

    @ThreadSafe
    public class AWSApplicationAutoScalingAsyncClient
    extends AWSApplicationAutoScalingClient
    implements AWSApplicationAutoScalingAsync
    Interface for accessing Application Auto Scaling asynchronously. Each asynchronous method will return a Java Future object representing the asynchronous operation; overloads which accept an 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.

    At this time, Application Auto Scaling only supports scaling Amazon ECS services.

    For example, you can use Application Auto Scaling to accomplish the following tasks:

    • Define scaling policies for automatically adjusting your application’s resources

    • Scale your resources in response to CloudWatch alarms

    • View history of your scaling events

      • AWSApplicationAutoScalingAsyncClient

        public AWSApplicationAutoScalingAsyncClient()
        Constructs a new asynchronous client to invoke service methods on Application Auto Scaling. A credentials provider chain will be used that searches for credentials in this order:
        • Environment Variables - AWS_ACCESS_KEY_ID and AWS_SECRET_KEY
        • Java System Properties - aws.accessKeyId and aws.secretKey
        • Credential profiles file at the default location (~/.aws/credentials) shared by all AWS SDKs and the AWS CLI
        • Instance profile credentials delivered through the Amazon EC2 metadata service

        Asynchronous methods are delegated to a fixed-size thread pool containing 50 threads (to match the default maximum number of concurrent connections to the service).

      • AWSApplicationAutoScalingAsyncClient

        public AWSApplicationAutoScalingAsyncClient​(ClientConfiguration clientConfiguration)
        Constructs a new asynchronous client to invoke service methods on Application Auto Scaling. A credentials provider chain will be used that searches for credentials in this order:
        • Environment Variables - AWS_ACCESS_KEY_ID and AWS_SECRET_KEY
        • Java System Properties - aws.accessKeyId and aws.secretKey
        • Credential profiles file at the default location (~/.aws/credentials) shared by all AWS SDKs and the AWS CLI
        • Instance profile credentials delivered through the Amazon EC2 metadata service

        Asynchronous methods are delegated to a fixed-size thread pool containing a number of threads equal to the maximum number of concurrent connections configured via ClientConfiguration.getMaxConnections().

        Parameters:
        clientConfiguration - The client configuration options controlling how this client connects to Application Auto Scaling (ex: proxy settings, retry counts, etc).

      • AWSApplicationAutoScalingAsyncClient

        public AWSApplicationAutoScalingAsyncClient​(AWSCredentials awsCredentials)
        Constructs a new asynchronous client to invoke service methods on Application Auto Scaling using the specified AWS account credentials.

        Asynchronous methods are delegated to a fixed-size thread pool containing 50 threads (to match the default maximum number of concurrent connections to the service).

        Parameters:
        awsCredentials - The AWS credentials (access key ID and secret key) to use when authenticating with AWS services.
