Elastic Load Balancing

Elastic Load Balancing is a cost-effective and easy to use web service to help you improve availability and scalability of your application. It makes it easy for you to distribute application loads between two or more EC2 instances. Elastic Load Balancing enables availability through redundancy and supports traffic growth of your application.

This guide provides detailed information about Elastic Load Balancing actions, data types, parameters, and errors.

Query requests are HTTP or HTTPS requests that use the HTTP verb GET or POST and a Query parameter named Action or Operation. Action is used throughout this documentation, although Operation is supported for backward compatibility with other AWS Query APIs.

This reference guide is based on the current WSDL, which is available at:

For detailed information on constructing a query request using the actions, data types, and parameters mentioned in this guide, go to Using the Query API in the Elastic Load Balancing Developer Guide .

Removes the specified EC2 Availability Zones from the set of configured Availability Zones for the LoadBalancer.

There must be at least one Availability Zone registered with a LoadBalancer at all times. A client cannot remove all the Availability Zones from a LoadBalancer. Once an Availability Zone is removed, all the instances registered with the LoadBalancer that are in the removed Availability Zone go into the OutOfService state. Upon Availability Zone removal, the LoadBalancer attempts to equally balance the traffic among its remaining usable Availability Zones. Trying to remove an Availability Zone that was not associated with the LoadBalancer does nothing.

NOTE: In order for this call to be successful, the client must have created the LoadBalancer. The client must provide the same account credentials as those that were used to create the LoadBalancer.

Specified by:

Parameters:

disableAvailabilityZonesForLoadBalancerRequest - Container for the necessary parameters to execute the DisableAvailabilityZonesForLoadBalancer service method on AmazonElasticLoadBalancing.

NOTE: LoadBalancer DNS names vary depending on the Region they're created in. For LoadBalancers created in the United States, the DNS name ends with: us-east-1.elb.amazonaws.com (for the US Standard Region) us-west-1.elb.amazonaws.com (for the Northern California Region) For LoadBalancers created in the EU (Ireland) Region, the DNS name ends with: eu-west-1.elb.amazonaws.com

                               AmazonClientException

Deletes the specified LoadBalancer.

If attempting to recreate the LoadBalancer, the client must reconfigure all the settings. The DNS name associated with a deleted LoadBalancer will no longer be usable. Once deleted, the name and associated DNS record of the LoadBalancer no longer exist and traffic sent to any of its IP addresses will no longer be delivered to client instances. The client will not receive the same DNS name even if a new LoadBalancer with same LoadBalancerName is created.

To successfully call this API, the client must provide the same account credentials as were used to create the LoadBalancer.

NOTE: By design, if the LoadBalancer does not exist or has already been deleted, DeleteLoadBalancer still succeeds.

Specified by:

deleteLoadBalancer in interface AmazonElasticLoadBalancing

Parameters:

deleteLoadBalancerRequest - Container for the necessary parameters to execute the DeleteLoadBalancer service method on AmazonElasticLoadBalancing.

Throws:

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.

Generates a stickiness policy with sticky session lifetimes controlled by the lifetime of the browser (user-agent) or a specified expiration period. This policy can be associated only with HTTP/HTTPS listeners.

When a LoadBalancer implements this policy, the LoadBalancer uses a special cookie to track the backend server instance for each request. When the LoadBalancer receives a request, it first checks to see if this cookie is present in the request. If so, the LoadBalancer sends the request to the application server specified in the cookie. If not, the LoadBalancer sends the request to a server that is chosen based on the existing load balancing algorithm.

A cookie is inserted into the response for binding subsequent requests from the same user to that server. The validity of the cookie is based on the cookie expiration time, which is specified in the policy configuration.

Specified by:

createLBCookieStickinessPolicy in interface AmazonElasticLoadBalancing

Parameters:

createLBCookieStickinessPolicyRequest - Container for the necessary parameters to execute the CreateLBCookieStickinessPolicy service method on AmazonElasticLoadBalancing.

Specified by:

attachLoadBalancerToSubnets in interface AmazonElasticLoadBalancing

Parameters:

attachLoadBalancerToSubnetsRequest - Container for the necessary parameters to execute the AttachLoadBalancerToSubnets service method on AmazonElasticLoadBalancing.

Returns:

The response from the AttachLoadBalancerToSubnets service method, as returned by AmazonElasticLoadBalancing.

Throws:

createAppCookieStickinessPolicy

public CreateAppCookieStickinessPolicyResult createAppCookieStickinessPolicy(CreateAppCookieStickinessPolicyRequest createAppCookieStickinessPolicyRequest)

                                                                             AmazonClientException

Generates a stickiness policy with sticky session lifetimes that follow that of an application-generated cookie. This policy can be associated only with HTTP/HTTPS listeners.

This policy is similar to the policy created by CreateLBCookieStickinessPolicy, except that the lifetime of the special Elastic Load Balancing cookie follows the lifetime of the application-generated cookie specified in the policy configuration. The LoadBalancer only inserts a new stickiness cookie when the application response includes a new application cookie.

If the application cookie is explicitly removed or expires, the session stops being sticky until a new application cookie is issued.

NOTE: An application client must receive and send two cookies: the application-generated cookie and the special Elastic Load Balancing cookie named AWSELB. This is the default behavior for many common web browsers.

Specified by:

createAppCookieStickinessPolicy in interface AmazonElasticLoadBalancing

Parameters:

createAppCookieStickinessPolicyRequest - Container for the necessary parameters to execute the CreateAppCookieStickinessPolicy service method on AmazonElasticLoadBalancing.

Returns:

The response from the CreateAppCookieStickinessPolicy service method, as returned by AmazonElasticLoadBalancing.

Throws:

InvalidConfigurationRequestException

Adds new instances to the LoadBalancer.

Once the instance is registered, it starts receiving traffic and requests from the LoadBalancer. Any instance that is not in any of the Availability Zones registered for the LoadBalancer will be moved to the OutOfService state. It will move to the InService state when the Availability Zone is added to the LoadBalancer.

NOTE: In order for this call to be successful, the client must have created the LoadBalancer. The client must provide the same account credentials as those that were used to create the LoadBalancer.

NOTE: Completion of this API does not guarantee that operation has completed. Rather, it means that the request has been registered and the changes will happen shortly.

getCachedResponseMetadata

public 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 the request.

Specified by:

getCachedResponseMetadata in interface AmazonElasticLoadBalancing

Parameters:

request - The originally executed request

Returns:

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