What you'll do

In this lab, you will migrate an application by using a blue/green and canary strategy.

  1. Configure and test a blue application environment that uses two Amazon Elastic Cloud (Amazon EC2) instances
  2. Configure a parallel green application environment that uses two EC2 instances
  3. Perform canary testing by using an Application Load Balancer
  4. Migrate fifty percent of the traffic to the green version
  5. Direct all traffic to the green EC2 instances and decommission the blue EC2 instances by using a CloudFormation change set

Note: Once you begin the lab, you will not be able to pause, save, or exit and then return to your lab. Please ensure that you have set aside enough time to complete the lab before you start.
