# This class is the starting point for working with Auto Scaling.
#
# To use Auto Scaling you must first
# [sign up here](http://aws.amazon.com/autoscaling/).
#
# For more information about Auto Scaling:
#
# * [Auto Scaling](http://aws.amazon.com/autoscaling/)
# * [Auto Scaling Documentation](http://aws.amazon.com/documentation/autoscaling/)
#
# # Credentials
#
# You can setup default credentials for all AWS services via
# AWS.config:
#
# AWS.config(
# :access_key_id => 'YOUR_ACCESS_KEY_ID',
# :secret_access_key => 'YOUR_SECRET_ACCESS_KEY')
#
# Or you can set them directly on the AWS::AutoScaling interface:
#
# auto_scaling = AWS::AutoScaling.new(
# :access_key_id => 'YOUR_ACCESS_KEY_ID',
# :secret_access_key => 'YOUR_SECRET_ACCESS_KEY')
#
# # Launch Configurations
#
# You need to create a launch configuration before you can create
# an Auto Scaling Group.
#
# # needs a name, image id, and instance type
# launch_config = auto_scaling.launch_configurations.create(
# 'launch-config-name', 'ami-12345', 'm1.small')
#
# If you have previously created a launch configuration you can
# reference using the {LaunchConfigurationCollection}.
#
# launch_config = auto_scaling.launch_configurations['launch-config-name']
#
# # Auto Scaling Groups
#
# Given a launch configuration, you can now create an Auto Scaling {Group}.
#
# group = auto_scaling.groups.create('group-name',
# :launch_configuration => launch_config,
# :availability_zones => %w(us-west-2a us-west-2b),
# :min_size => 1,
# :max_size => 4)
#
# @!attribute [r] client
# @return [Client] the low-level AutoScaling client object
