  - createAppCookieStickinessPolicy
```
public CreateAppCookieStickinessPolicyResult createAppCookieStickinessPolicy(CreateAppCookieStickinessPolicyRequest createAppCookieStickinessPolicyRequest)
```
    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 Elastic Load Balancing Developer Guide.
    
    Specified by:
    
    createAppCookieStickinessPolicy in interface AmazonElasticLoadBalancing
    
    Parameters:
    
    createAppCookieStickinessPolicyRequest -
    
    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.
  - createLBCookieStickinessPolicy
```
public CreateLBCookieStickinessPolicyResult createLBCookieStickinessPolicy(CreateLBCookieStickinessPolicyRequest createLBCookieStickinessPolicyRequest)
```
    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 back-end 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.
    
    For more information, see Duration-Based Session Stickiness in the Elastic Load Balancing Developer Guide.

  - createLoadBalancer
```
public CreateLoadBalancerResult createLoadBalancer(CreateLoadBalancerRequest createLoadBalancerRequest)
```
    Creates a load balancer.
    
    If the call completes successfully, a new load balancer is created with a unique Domain Name Service (DNS) name. The load balancer receives incoming traffic and routes it to the registered instances. For more information, see How Elastic Load Balancing Works in the Elastic Load Balancing Developer Guide.
    
    You can create up to 20 load balancers per region per account. You can request an increase for the number of load balancers for your account. For more information, see Elastic Load Balancing Limits in the Elastic Load Balancing Developer Guide.

    The load balancer evenly distributes requests across all its registered Availability Zones that contain instances.
    
    For more information, see Add Availability Zone in the Elastic Load Balancing Developer Guide.
    
    Specified by:
    
    enableAvailabilityZonesForLoadBalancer in interface AmazonElasticLoadBalancing
    
    Parameters:
    
    enableAvailabilityZonesForLoadBalancerRequest -
    
    Returns:
    
    Result of the EnableAvailabilityZonesForLoadBalancer operation returned by the service.
    
    Throws:
    
    LoadBalancerNotFoundException - The specified load balancer does not exist.
  - modifyLoadBalancerAttributes
```
public ModifyLoadBalancerAttributesResult modifyLoadBalancerAttributes(ModifyLoadBalancerAttributesRequest modifyLoadBalancerAttributesRequest)
```
    Modifies the attributes of the specified load balancer.
    
    You can modify the load balancer attributes, such as AccessLogs, ConnectionDraining, and CrossZoneLoadBalancing by either enabling or disabling them. Or, you can modify the load balancer attribute ConnectionSettings by specifying an idle connection timeout value for your load balancer.
    
    For more information, see the following in the Elastic Load Balancing Developer Guide:
    Specified by:
    
    modifyLoadBalancerAttributes in interface AmazonElasticLoadBalancing
    
    Parameters:
    
    modifyLoadBalancerAttributesRequest -
    
    Returns:
    
    Result of the ModifyLoadBalancerAttributes operation returned by the service.
    
    Throws:
    
    LoadBalancerNotFoundException - The specified load balancer does not exist.
    
    LoadBalancerAttributeNotFoundException - The specified load balancer attribute does not exist.
    
    InvalidConfigurationRequestException - The requested configuration change is not valid.
  - registerInstancesWithLoadBalancer
```
public RegisterInstancesWithLoadBalancerResult registerInstancesWithLoadBalancer(RegisterInstancesWithLoadBalancerRequest registerInstancesWithLoadBalancerRequest)
```
    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.
    
    If you stop an instance registered with a load balancer and then start it, the IP addresses associated with the instance changes. Elastic Load Balancing cannot recognize the new IP address, which prevents it from routing traffic to the instances. We recommend that you use the following sequence: stop the instance, deregister the instance, start the instance, and then register the instance. To deregister instances from a load balancer, use DeregisterInstancesFromLoadBalancer.
    
    For more information, see Deregister and Register EC2 Instances in the Elastic Load Balancing Developer Guide.
    
    Specified by:
    
    registerInstancesWithLoadBalancer in interface AmazonElasticLoadBalancing
    
    Parameters:
    
    registerInstancesWithLoadBalancerRequest -
    
    Returns:
    
    Result of the RegisterInstancesWithLoadBalancer operation returned by the service.
    
    Throws:
    
    LoadBalancerNotFoundException - The specified load balancer does not exist.
    
    InvalidInstanceException - The specified endpoint is not valid.
  - removeTags
```
public RemoveTagsResult removeTags(RemoveTagsRequest removeTagsRequest)
```
    Removes one or more tags from the specified load balancer.
    
    Specified by:
    
    removeTags in interface AmazonElasticLoadBalancing
    
    Parameters:
    
    removeTagsRequest -
    
    Returns:
    
    Result of the RemoveTags operation returned by the service.
    
    Throws:
    
    LoadBalancerNotFoundException - The specified load balancer does not exist.
  - setLoadBalancerListenerSSLCertificate
```
public SetLoadBalancerListenerSSLCertificateResult setLoadBalancerListenerSSLCertificate(SetLoadBalancerListenerSSLCertificateRequest setLoadBalancerListenerSSLCertificateRequest)
```
    Sets the certificate that terminates the specified listener's SSL connections. The specified certificate replaces any prior certificate that was used on the same load balancer and port.
    
    For more information about updating your SSL certificate, see Updating an SSL Certificate for a Load Balancer in the Elastic Load Balancing Developer Guide.
    
    Specified by:
    
    setLoadBalancerListenerSSLCertificate in interface AmazonElasticLoadBalancing
    
    Parameters:
    
    setLoadBalancerListenerSSLCertificateRequest -
    
    Returns:
    
    Result of the SetLoadBalancerListenerSSLCertificate operation returned by the service.
    
    Throws:
    
    CertificateNotFoundException - The specified SSL ID does not refer to a valid SSL certificate in AWS Identity and Access Management (IAM).
    
    LoadBalancerNotFoundException - The specified load balancer does not exist.
    
    ListenerNotFoundException - The load balancer does not have a listener configured at the specified port.
    
    InvalidConfigurationRequestException - The requested configuration change is not valid.
  - setLoadBalancerPoliciesForBackendServer
```
public SetLoadBalancerPoliciesForBackendServerResult setLoadBalancerPoliciesForBackendServer(SetLoadBalancerPoliciesForBackendServerRequest setLoadBalancerPoliciesForBackendServerRequest)
```
    Replaces the set of policies associated with the specified port on which the back-end server is listening with a new set of policies. At this time, only the back-end server authentication policy type can be applied to the back-end ports; this policy type is composed of multiple public key policies.
    
    Each time you use SetLoadBalancerPoliciesForBackendServer to enable the policies, use the PolicyNames parameter to list the policies that you want to enable.
    
    You can use DescribeLoadBalancers or DescribeLoadBalancerPolicies to verify that the policy is associated with the back-end server.
    
    Specified by:
    
    setLoadBalancerPoliciesForBackendServer in interface AmazonElasticLoadBalancing
    
    Parameters:
    
    setLoadBalancerPoliciesForBackendServerRequest -

    Result of the SetLoadBalancerPoliciesOfListener operation returned by the service.
    
    Throws:
    
    LoadBalancerNotFoundException - The specified load balancer does not exist.
    
    PolicyNotFoundException - One or more of the specified policies do not exist.
    
    ListenerNotFoundException - The load balancer does not have a listener configured at the specified port.
    
    InvalidConfigurationRequestException - The requested configuration change is not valid.
  - 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.
