This lesson focuses on how to perform blue/green deployments using Auto Scaling groups in the AWS Management Console. In this lesson, we will not use Route 53 to facilitate a blue/green deployment. Instead, we will attach a second Auto Scaling group (Green) to the Elastic Load Balancer and gradually increase it to the desired size. We will then decommission the instances in the original Auto Scaling group.
