/**
 * <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 the following types of load balancers: Application Load Balancers, Network Load
 * Balancers, Gateway Load Balancers, and Classic Load Balancers. This reference covers the following load balancer
 * types:
 * </p>
 * <ul>
 * <li>
 * <p>
 * Application Load Balancer - Operates at the application layer (layer 7) and supports HTTP and HTTPS.
 * </p>
 * </li>
 * <li>
 * <p>
 * Network Load Balancer - Operates at the transport layer (layer 4) and supports TCP, TLS, and UDP.
 * </p>
 * </li>
 * <li>
 * <p>
 * Gateway Load Balancer - Operates at the network layer (layer 3).
 * </p>
 * </li>
 * </ul>
 * <p>
 * For more information, see the <a href="https://docs.aws.amazon.com/elasticloadbalancing/latest/userguide/">Elastic
 * Load Balancing User Guide</a>.
 * </p>
 * <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>
