// 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.
//
// 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 Elastic
// Load Balancing User Guide (http://docs.aws.amazon.com/elasticloadbalancing/latest/userguide/).
//
// This reference covers the 2015-12-01 API, which supports Application load
// balancers. The 2012-06-01 API supports Classic load balancers.
//
// To get started with an Application load balancer, complete the following
// tasks:
//
//   Create a load balancer using CreateLoadBalancer.
//
//   Create a target group using CreateTargetGroup.
//
//   Register targets for the target group using RegisterTargets.
//
//   Create one or more listeners for your load balancer using CreateListener.
//
//   (Optional) Create one or more rules for content routing based on URL using
// CreateRule.
//
//   To delete an Application load balancer and its related resources, complete
// the following tasks:
//
//   Delete the load balancer using DeleteLoadBalancer.
//
//   Delete the target group using DeleteTargetGroup.
//
//   All Elastic Load Balancing operations are idempotent, which means that
// they complete at most one time. If you repeat an operation, it succeeds.
//The service client's operations are safe to be used concurrently.
// It is not safe to mutate any of the client's properties though.
