Auto Scaling in Amazon Web Services (AWS) automatically adds or removes compute resources running your application in the cloud-based on conditions you configure. For applications configured to run on a cloud infrastructure, scaling is an important part of cost control and resource management.

You will create an Auto Scaling Group and place its instances behind a Classic Elastic Load Balancer (ELB). Don't worry if you don't fully understand all the components yet. Each one will be discussed in greater detail as you create and configure them. At the end of this lab, you will have an Auto Scaling Group with several web server instances behind a Classic ELB. If you are interested in using the newer Network Load Balancer, try this other Lab on Auto Scaling and load balancing.
