/**
* Interface for accessing AmazonAutoScaling asynchronously,

*
* Amazon Auto Scaling is an easy-to-use web service designed to
* automatically launch or terminate EC2 instances based on user defined
* triggers. Users can set up Auto Scaling groups and associate triggers
* with these groups to automatically scale computing resources based on
* parameters such as bandwidth usage or CPU utilization. Auto Scaling
* groups can work across multiple Availability Zones - distinct physical
* locations for the hosted EC2 instances - so that if an Availability
* Zone becomes unhealthy or unavailable, Auto Scaling will automatically
* re-distribute applications to a healthy Availability Zone.
