## 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.

- Amazon ECS services
- Amazon EC2 Spot fleet instances
You can use Application Auto Scaling to accomplish the following tasks:
- Define scaling policies for automatically adjusting your AWS 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).
