# Amazon Elastic Load Balancing SDK * [Version](#version) * [Description](#description) * [Contribute](#contribute) * [Licence](#licence) ## Version `1.3.7` ## Description Elastic Load Balancing Elastic Load Balancing distributes incoming traffic across your EC2 instances. For information about the features of Elastic Load Balancing, see in the /Elastic Load Balancing Developer Guide/. For information about the AWS regions supported by Elastic Load Balancing, see in the /Amazon Web Services General Reference/. 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. Documentation is available via [Hackage](http://hackage.haskell.org/package/amazonka-elb) and the [AWS API Reference](http://docs.aws.amazon.com/ElasticLoadBalancing/latest/APIReference/Welcome.html). The types from this library are intended to be used with [amazonka](http://hackage.haskell.org/package/amazonka), which provides mechanisms for specifying AuthN/AuthZ information and sending requests. Use of lenses is required for constructing and manipulating types. This is due to the amount of nesting of AWS types and transparency regarding de/serialisation into more palatable Haskell values. The provided lenses should be compatible with any of the major lens libraries [lens](http://hackage.haskell.org/package/lens) or [lens-family-core](http://hackage.haskell.org/package/lens-family-core). ## Contribute For any problems, comments, or feedback please create an issue [here on GitHub](https://github.com/brendanhay/amazonka/issues). > _Note:_ this library is an auto-generated Haskell package. Please see `amazonka-gen` for more information. ## Licence `amazonka-elb` is released under the [Mozilla Public License Version 2.0](http://www.mozilla.org/MPL/).
