/**
 * <fullname>Elastic Load Balancing</fullname>
 * <p>
 * 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.
 * </p>
 * <p>
 * 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 <a
 * href="http://docs.aws.amazon.com/elasticloadbalancing/latest/userguide/what-is-load-balancing.html">Elastic Load
 * Balancing User Guide</a>.
 * </p>
 * <p>
 * This reference covers the 2012-06-01 API, which supports Classic Load Balancers. The 2015-12-01 API supports
 * Application Load Balancers.
 * </p>
 * <p>
 * To get started, create a load balancer with one or more listeners using <a>CreateLoadBalancer</a>. Register your
 * instances with the load balancer using <a>RegisterInstancesWithLoadBalancer</a>.
 * </p>
 * <p>
 * All Elastic Load Balancing operations are <i>idempotent</i>, which means that they complete at most one time. If you
 * repeat an operation, it succeeds with a 200 OK response code.
 * </p>
