public class AmazonElasticLoadBalancingClient
extends AmazonWebServiceClient
implements AmazonElasticLoadBalancing

Client for accessing Elastic Load Balancing. All service calls made using this client are blocking, and will not return until the service call completes.

Elastic Load Balancing

A load balancer distributes incoming traffic across your EC2 instances. This enables you to increase the availability of your application. The load balancer also monitors the health of its registered instances and ensures that it routes traffic only to healthy instances. You configure your load balancer to accept incoming traffic by specifying one or more listeners, which are configured with a protocol and port number for connections from clients to the load balancer and a protocol and port number for connections from the load balancer to the instances.

Elastic Load Balancing supports two types of load balancers: Classic Load Balancers and Application Load Balancers (new). A Classic Load Balancer makes routing and load balancing decisions either at the transport layer (TCP/SSL) or the application layer (HTTP/HTTPS), and supports either EC2-Classic or a VPC. An Application Load Balancer makes routing and load balancing decisions at the application layer (HTTP/HTTPS), supports path-based routing, and can route requests to one or more ports on each EC2 instance or container instance in your virtual private cloud (VPC). For more information, see the Elastic Load Balancing User Guide.

This reference covers the 2012-06-01 API, which supports Classic Load Balancers. The 2015-12-01 API supports Application Load Balancers.

To get started, create a load balancer with one or more listeners using CreateLoadBalancer. Register your instances with the load balancer using RegisterInstancesWithLoadBalancer.

All Elastic Load Balancing operations are idempotent, which means that they complete at most one time. If you repeat an operation, it succeeds with a 200 OK response code.

createAppCookieStickinessPolicy

public CreateAppCookieStickinessPolicyResult createAppCookieStickinessPolicy(CreateAppCookieStickinessPolicyRequest request)

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, AWSELB, follows the lifetime of the application-generated cookie specified in the policy configuration. The load balancer 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.

For more information, see Application-Controlled Session Stickiness in the Classic Load Balancer Guide.

Specified by:

createAppCookieStickinessPolicy in interface AmazonElasticLoadBalancing

Parameters:

createAppCookieStickinessPolicyRequest - Contains the parameters for CreateAppCookieStickinessPolicy.

Returns:

Result of the CreateAppCookieStickinessPolicy operation returned by the service.

Throws:

LoadBalancerNotFoundException - The specified load balancer does not exist.

DuplicatePolicyNameException - A policy with the specified name already exists for this load balancer.

TooManyPoliciesException - The quota for the number of policies for this load balancer has been reached.

InvalidConfigurationRequestException - The requested configuration change is not valid.

See Also:

AWS API Documentation

createLBCookieStickinessPolicy

public CreateLBCookieStickinessPolicyResult createLBCookieStickinessPolicy(CreateLBCookieStickinessPolicyRequest request)

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 load balancer implements this policy, the load balancer uses a special cookie to track the instance for each request. When the load balancer receives a request, it first checks to see if this cookie is present in the request. If so, the load balancer sends the request to the application server specified in the cookie. If not, the load balancer 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.

For more information, see Duration-Based Session Stickiness in the Classic Load Balancer Guide.

Specified by:

createLBCookieStickinessPolicy in interface AmazonElasticLoadBalancing

Parameters:

createLBCookieStickinessPolicyRequest - Contains the parameters for CreateLBCookieStickinessPolicy.

Returns:

Result of the CreateLBCookieStickinessPolicy operation returned by the service.

Throws:

LoadBalancerNotFoundException - The specified load balancer does not exist.

DuplicatePolicyNameException - A policy with the specified name already exists for this load balancer.

TooManyPoliciesException - The quota for the number of policies for this load balancer has been reached.

InvalidConfigurationRequestException - The requested configuration change is not valid.

registerInstancesWithLoadBalancer

public RegisterInstancesWithLoadBalancerResult registerInstancesWithLoadBalancer(RegisterInstancesWithLoadBalancerRequest request)

Adds the specified instances to the specified load balancer.

The instance must be a running instance in the same network as the load balancer (EC2-Classic or the same VPC). If you have EC2-Classic instances and a load balancer in a VPC with ClassicLink enabled, you can link the EC2-Classic instances to that VPC and then register the linked EC2-Classic instances with the load balancer in the VPC.

Note that RegisterInstanceWithLoadBalancer completes when the request has been registered. Instance registration takes a little time to complete. To check the state of the registered instances, use DescribeLoadBalancers or DescribeInstanceHealth.

After the instance is registered, it starts receiving traffic and requests from the load balancer. Any instance that is not in one of the Availability Zones registered for the load balancer is moved to the OutOfService state. If an Availability Zone is added to the load balancer later, any instances registered with the load balancer move to the InService state.

To deregister instances from a load balancer, use DeregisterInstancesFromLoadBalancer.

For more information, see Register or De-Register EC2 Instances in the Classic Load Balancer Guide.

Specified by:

registerInstancesWithLoadBalancer in interface AmazonElasticLoadBalancing

Parameters:

registerInstancesWithLoadBalancerRequest - Contains the parameters for RegisterInstancesWithLoadBalancer.

Returns:

Result of the RegisterInstancesWithLoadBalancer operation returned by the service.

Throws:

LoadBalancerNotFoundException - The specified load balancer does not exist.

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.
