In one line
Free. Auto Scaling has no charge of its own - you pay only for the instances it launches.
This service turns no meters of its own. Read the trap below for what it makes you pay for elsewhere.
What gets missed
The service is free, but the CloudWatch alarms and detailed monitoring that drive it are not, and every launch re-triggers the per-instance billing minimum.
Bills the same way
These services turn exactly the same meters, so what you learn here transfers.
