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 toin the Elastic Load Balancing Developer Guide .

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, seein the Amazon Web Services General Reference.
