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 only be associated only with HTTP listeners.

When a load balancer implements this policy, the load balancer uses a special cookie to track the backend server 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.

Parameters:: createLBCookieStickinessPolicyRequest - Container for the necessary parameters to execute the CreateLBCookieStickinessPolicy operation on AmazonElasticLoadBalancing.
Returns:: A Java Future object containing the response from the CreateLBCookieStickinessPolicy service method, as returned by AmazonElasticLoadBalancing.

Creates a new LoadBalancer.

Once the call has completed successfully, a new LoadBalancer is created; however, it will not be usable until at least one instance has been registered. When the LoadBalancer creation is completed, the client can check whether or not it is usable by using the DescribeInstanceHealth API. The LoadBalancer is usable as soon as any registered instance is InService .

NOTE: Currently, the client's quota of LoadBalancers is limited to five per Region.

NOTE: Load balancer DNS names vary depending on the Region they're created in. For load balancers 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 load balancers created in the EU (Ireland) Region, the DNS name ends with: eu-west-1.elb.amazonaws.com

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.

Parameters:: registerInstancesWithLoadBalancerRequest - Container for the necessary parameters to execute the RegisterInstancesWithLoadBalancer operation on AmazonElasticLoadBalancing.
Returns:: A Java Future object containing the response from the RegisterInstancesWithLoadBalancer service method, as returned by AmazonElasticLoadBalancing.

                                                                                          AmazonClientException

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

Parameters:: createAppCookieStickinessPolicyRequest - Container for the necessary parameters to execute the CreateAppCookieStickinessPolicy operation on AmazonElasticLoadBalancing.
Returns:: A Java Future object containing the response from the CreateAppCookieStickinessPolicy service method, as returned by 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.; AmazonServiceException - If an error response is returned by AmazonElasticLoadBalancing indicating either a problem with the data in the request, or a server side issue.

deleteLoadBalancerAsync

Future<Void> deleteLoadBalancerAsync(DeleteLoadBalancerRequest deleteLoadBalancerRequest)
                                     throws AmazonServiceException,
                                            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.

Parameters:: deleteLoadBalancerRequest - Container for the necessary parameters to execute the DeleteLoadBalancer operation on AmazonElasticLoadBalancing.
Returns:: A Java Future object containing the response from the DeleteLoadBalancer service method, as returned by 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.; AmazonServiceException - If an error response is returned by AmazonElasticLoadBalancing indicating either a problem with the data in the request, or a server side issue.

disableAvailabilityZonesForLoadBalancerAsync

Future<DisableAvailabilityZonesForLoadBalancerResult> disableAvailabilityZonesForLoadBalancerAsync(DisableAvailabilityZonesForLoadBalancerRequest disableAvailabilityZonesForLoadBalancerRequest)
                                                                                                   throws AmazonServiceException,

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.

Parameters:: disableAvailabilityZonesForLoadBalancerRequest - Container for the necessary parameters to execute the DisableAvailabilityZonesForLoadBalancer operation on AmazonElasticLoadBalancing.
Returns:: A Java Future object containing the response from the DisableAvailabilityZonesForLoadBalancer service method, as returned by 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.; AmazonServiceException - If an error response is returned by AmazonElasticLoadBalancing indicating either a problem with the data in the request, or a server side issue.
