/**
* <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>
