This script creates an AutoScale Group of EC2 instances with NGINX running on them. In case of CPU metric crosses 80 percent - It will create a new instance to spread the load and will assign it to the same ELB so the user won't feel anything. Minimum instances - 1. Maximum instances - 5. Cooldown is set for 600sec because it takes a lot of time for the NGINX servers to be installed and run.
