The AWS resource description template lists all of your resources and their attributes. CloudFormation will automatically set up the Auto Scaling group, load balancer, and database when you use this template to create a stack. When the stack is created, your AWS assets will immediately become operational. You can just as easily remove the stack, which will free up any resources it previously held. You can control multiple resources as if they were one with the help of CloudFormation. The combination of an Auto Scaling group, an Elastic Load Balancing load balancer, and an Amazon Relational Database Service database instance can allow for a highly available and scalable web application with a database backend.
