public interface AmazonAutoScaling

Interface for accessing AmazonAutoScaling. Auto Scaling

Auto Scaling is a web service designed to automatically launch or terminate EC2 instances based on user-defined policies, schedules, and health checks. Auto Scaling responds automatically to changing conditions. All you need to do is specify how it should respond to those changes.

Auto Scaling groups can work across multiple Availability Zones - distinct physical locations for the hosted Amazon EC2 instances - so that if an Availability Zone becomes unavailable, Auto Scaling will automatically redistribute applications to a different Availability Zone.

Every API call returns a response meta data object that contains a request identifier. Successful requests return an HTTP 200 status code. Unsuccessful requests return an error object and an HTTP status code of 400 or 500.

The current WSDL is available at:

Method Detail

setEndpoint

void setEndpoint(String endpoint)
                 throws IllegalArgumentException

Overrides the default endpoint for this client ("https://autoscaling.amazonaws.com"). Callers can use this method to control which AWS region they want to work with.

Callers can pass in just the endpoint (ex: "ec2.amazonaws.com") or a full URL, including the protocol (ex: "https://ec2.amazonaws.com"). If the protocol is not specified here, the default protocol from this client's ClientConfiguration will be used, which by default is HTTPS.

For more information on using AWS regions with the AWS SDK for Java, and a complete list of all available endpoints for all AWS services, see: http://developer.amazonwebservices.com/connect/entry.jspa?externalID=3912

Parameters:

endpoint - The endpoint (ex: "ec2.amazonaws.com") or a full URL, including the protocol (ex: "https://ec2.amazonaws.com") of the region specific AWS endpoint this client will communicate with.

Throws:

IllegalArgumentException - If any problems are detected with the specified endpoint.

putScheduledUpdateGroupAction

void putScheduledUpdateGroupAction(PutScheduledUpdateGroupActionRequest putScheduledUpdateGroupActionRequest)
                                   throws AmazonServiceException,
                                          AmazonClientException

Creates a scheduled scaling action for a Auto Scaling group. If you leave a parameter unspecified, the corresponding value remains unchanged in the affected Auto Scaling group.

Parameters:

putScheduledUpdateGroupActionRequest - Container for the necessary parameters to execute the PutScheduledUpdateGroupAction service method on AmazonAutoScaling.

Throws:

AlreadyExistsException

LimitExceededException

AmazonClientException - If any internal errors are encountered inside the client while attempting to make the request or handle the response. For example if a network connection is not available.

AmazonServiceException - If an error response is returned by AmazonAutoScaling indicating either a problem with the data in the request, or a server side issue.

setDesiredCapacity

void setDesiredCapacity(SetDesiredCapacityRequest setDesiredCapacityRequest)
                        throws AmazonServiceException,
                               AmazonClientException

Adjusts the desired size of the AutoScalingGroup by initiating scaling activities. When reducing the size of the group, it is not possible to define which EC2 instances will be terminated. This applies to any auto-scaling decisions that might result in terminating instances.

There are two common use cases for SetDesiredCapacity : one for users of the Auto Scaling triggering system, and another for developers who write their own triggering systems. Both use cases relate to the concept of cooldown.

In the first case, if you use the Auto Scaling triggering system, SetDesiredCapacity changes the size of your Auto Scaling group without regard to the cooldown period. This could be useful, for example, if Auto Scaling did something unexpected for some reason. If your cooldown period is 10 minutes, Auto Scaling would normally reject requests to change the size of the group for that entire 10 minute period. The SetDesiredCapacity command allows you to circumvent this restriction and change the size of the group before the end of the cooldown period.

In the second case, if you write your own triggering system, you can use SetDesiredCapacity to control the size of your Auto Scaling group. If you want the same cooldown functionality that Auto Scaling offers, you can configure SetDesiredCapacity to honor cooldown by setting the HonorCooldown parameter to true .

Parameters:

setDesiredCapacityRequest - Container for the necessary parameters to execute the SetDesiredCapacity service method on AmazonAutoScaling.

Throws:

ScalingActivityInProgressException

AmazonClientException - If any internal errors are encountered inside the client while attempting to make the request or handle the response. For example if a network connection is not available.

AmazonServiceException - If an error response is returned by AmazonAutoScaling indicating either a problem with the data in the request, or a server side issue.

shutdown

void shutdown()

Shuts down this client object, releasing any resources that might be held open. This is an optional method, and callers are not expected to call it, but can if they want to explicitly release any open resources. Once a client has been shutdown, it should not be used to make any more requests.

getCachedResponseMetadata

ResponseMetadata getCachedResponseMetadata(AmazonWebServiceRequest request)

Returns additional metadata for a previously executed successful request, typically used for debugging issues where a service isn't acting as expected. This data isn't considered part of the result data returned by an operation, so it's available through this separate, diagnostic interface.

Response metadata is only cached for a limited period of time, so if you need to access this extra diagnostic information for an executed request, you should use this method to retrieve it as soon as possible after executing a request.

Parameters:

request - The originally executed request.

Returns:

The response metadata for the specified request, or null if none is available.
