  Elastic Load Balancing

  A load balancer can distribute 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.

  Elastic Load Balancing supports three types of load balancers: Application Load
  Balancers, Network Load Balancers,
  and Classic Load Balancers. You can select a load balancer based on your
  application needs. For more
  information, see the [Elastic Load Balancing User Guide](https://docs.aws.amazon.com/elasticloadbalancing/latest/userguide/).

  This reference covers the 2012-06-01 API, which supports Classic Load Balancers.
  The 2015-12-01 API supports Application Load Balancers and Network Load
  Balancers.

  To get started, create a load balancer with one or more listeners using
  `CreateLoadBalancer`.
  Register your instances with the load balancer using
  `RegisterInstancesWithLoadBalancer`.

  All Elastic Load Balancing operations are *idempotent*, which means
  that they complete at most one time. If you repeat an operation, it succeeds
  with a 200 OK
  response code.

  Generates a stickiness policy with sticky session lifetimes controlled by the
  lifetime of the browser (user-agent) or a specified expiration period.

  This policy can be associated only with HTTP/HTTPS listeners.

  When a load balancer implements this policy, the load balancer uses a special
  cookie to track the instance for each request. When the load balancer receives a
  request, it first checks to see if this cookie is present in the request.
  If so, the load balancer sends the request to the application server specified
  in the cookie. If not, the load balancer sends the request to a server that is
  chosen based on the existing load-balancing algorithm.

  A cookie is inserted into the response for binding subsequent requests from the
  same user to that server. The validity of the cookie is based on the cookie
  expiration time, which is specified in the policy configuration.
