/**
 * <fullname>Elastic Load Balancing</fullname>
 * <p>
 * A load balancer distributes incoming traffic across targets, such as your EC2 instances. This enables you to increase
 * the availability of your application. The load balancer also monitors the health of its registered targets and
 * ensures that it routes traffic only to healthy targets. 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. You configure a target group with a protocol and port number for connections from the
 * load balancer to the targets, and with health check settings to be used when checking the health status of the
 * targets.
 * </p>
 * <p>
 * Elastic Load Balancing supports two types of load balancers: Classic Load Balancers and Application Load Balancers. 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 <a href="http://docs.aws.amazon.com/elasticloadbalancing/latest/userguide/">Elastic Load
 * Balancing User Guide</a>.
 * </p>
 * <p>
 * This reference covers the 2015-12-01 API, which supports Application Load Balancers. The 2012-06-01 API supports
 * Classic Load Balancers.
 * </p>
 * <p>
 * To get started, complete the following tasks:
 * </p>
 * <ol>
 * <li>
 * <p>
 * Create an Application Load Balancer using <a>CreateLoadBalancer</a>.
 * </p>
 * </li>
 * <li>
 * <p>
 * Create a target group using <a>CreateTargetGroup</a>.
 * </p>
 * </li>
 * <li>
 * <p>
 * Register targets for the target group using <a>RegisterTargets</a>.
 * </p>
 * </li>
 * <li>
 * <p>
 * Create one or more listeners for your load balancer using <a>CreateListener</a>.
 * </p>
 * </li>
 * <li>
 * <p>
 * (Optional) Create one or more rules for content routing based on URL using <a>CreateRule</a>.
 * </p>
 * </li>
 * </ol>
 * <p>
 * To delete an Application Load Balancer and its related resources, complete the following tasks:
 * </p>
 * <ol>
 * <li>
 * <p>
 * Delete the load balancer using <a>DeleteLoadBalancer</a>.
 * </p>
 * </li>
 * <li>
 * <p>
 * Delete the target group using <a>DeleteTargetGroup</a>.
 * </p>
 * </li>
 * </ol>
 * <p>
 * All Elastic Load Balancing operations are idempotent, which means that they complete at most one time. If you repeat
 * an operation, it succeeds.
 * </p>
