/**
* Interface for accessing AmazonElasticLoadBalancing.
* Elastic Load Balancing
* Elastic Load Balancing is a cost-effective and easy to use web
* service to help you improve the availability and scalability of your
* application running on Amazon Elastic Cloud Compute (Amazon EC2). It
* makes it easy for you to distribute application loads between two or
* more EC2 instances. Elastic Load Balancing supports the growth in
* traffic of your application by enabling availability through
* redundancy.
*
*
* This guide provides detailed information about Elastic Load Balancing
* actions, data types, and parameters that can be used for sending a
* query request. Query requests are HTTP or HTTPS requests that use the
* HTTP verb GET or POST and a query parameter named Action or Operation.
* Action is used throughout this documentation, although Operation is
* supported for backward compatibility with other AWS Query APIs.
*
*
* For detailed information on constructing a query request using the
* actions, data types, and parameters mentioned in this guide, go to
* Using the Query API
* in the Elastic Load Balancing Developer Guide .
*
*
* For detailed information about Elastic Load Balancing features and
* their associated actions, go to
* Using Elastic Load Balancing
* in the Elastic Load Balancing Developer Guide .
*
*
* This reference guide is based on the current WSDL, which is available
* at:
*
*
*
*
* Endpoints
*
*
* The examples in this guide assume that your load balancers are created
* in the US East (Northern Virginia) region and use us-east-1 as the
* endpoint.
*
*
* You can create your load balancers in other AWS regions. For
* information about regions and endpoints supported by Elastic Load
* Balancing, see
* Regions and Endpoints
* in the Amazon Web Services General Reference.
