CloudFormation Change Sets and Drift Detection

Deploy a CloudFormation stack, preview a change with a change set, execute it, then intentionally drift a resource out-of-band and detect it with drift detection.

CloudFormation Change Sets and Drift Detection - Platform Engineering Hands-On Lab Icon

Lab Overview

Change sets let you preview what CloudFormation will modify before it touches your live stack. Drift detection tells you when someone (or something) has changed a resource outside CloudFormation. Together they form the control plane for governed infrastructure updates.

In this lab you will:

  • Author a CloudFormation template with an S3 bucket and an SQS queue, and deploy it as a stack
  • Modify the template and create a change set to preview every resource-level change
  • Execute the change set and verify the stack updates correctly
  • Deliberately modify an S3 bucket tag outside CloudFormation, then run drift detection to find it
  • Explore remediation options and clean up
