DevOps — Canary Deployment

Canary Deployment releases new features to a small group of users first. If the new version works well, it's gradually rolled out to everyone. This strategy helps detect issues early without impacting all users. It's like testing a change on a small sample before going fully live. Canary releases are often automated with tools like Kubernetes, ArgoCD, or Spinnaker.

Example: A streaming platform releases a new video player to 5% of users, then increases the rollout if no bugs are found.
