Amazon EC2 Auto Scaling

name: Amazon EC2 Auto Scaling
description: Amazon EC2 Auto Scaling helps you maintain application availability and lets you automatically add or remove
  EC2 instances according to conditions you define. You can use fleet management features to maintain the health and availability
  of your fleet, and use dynamic and predictive scaling to add or remove EC2 instances to meet demand.
