# Amazon Application Auto Scaling SDK * [Version](#version) * [Description](#description) * [Contribute](#contribute) * [Licence](#licence) ## Version `1.4.2` ## Description Application Auto Scaling is a general purpose Auto Scaling service for supported elastic AWS resources. With Application Auto Scaling, you can automatically scale your AWS resources, with an experience similar to that of Auto Scaling. At this time, Application Auto Scaling only supports scaling Amazon ECS services. For example, you can use Application Auto Scaling to accomplish the following tasks: - Define scaling policies for automatically adjusting your application’s resources - Scale your resources in response to CloudWatch alarms - View history of your scaling events Documentation is available via [Hackage](http://hackage.haskell.org/package/amazonka-application-autoscaling) and the [AWS API Reference](https://aws.amazon.com/documentation/). 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.
