-- * 'sdcHonorCooldown' - By default, @SetDesiredCapacity@ overrides any cooldown period associated with the Auto Scaling group.

-- * 'sdcAutoScalingGroupName' - The name of the Auto Scaling group.
--
-- * 'sdcDesiredCapacity' - The number of EC2 instances that should be running in the Auto Scaling group.
