EC2 Image Builder as an Artifact
Explore how EC2 Image Builder produces immutable AMIs used as deployable artifacts for reliable instance replacement. Understand building validation checklists, regression detection methods, and managing AMI versions to reduce drift and simplify rollback during incidents. This lesson enhances your ability to apply an evidence-driven approach for managing EC2 instances effectively.
We'll cover the following...
Fixing a live instance by hand feels fast, and that's exactly the problem with it. The change works, the symptom clears, but nothing records what was touched, so the fix can't be reproduced and the drift can't be proven later. An AMI produced by EC2 Image Builder solves this by behaving like a deployable artifact rather than a patch: it replaces instances through a launch template and an Auto Scaling rollout, leaving behind concrete identifiers, an AMI ID, a build, a version, that can be pointed to when something breaks. ...
