CI/CD Engineering: Blue/Green Deployments & Atomic Rollbacks

By Academic Curriculum & Technical Education Board

Curriculum Core Competency

Mastering deployment pipelines: automated test gating, atomic Nginx upstream switching, dual-slot convergence, and automated instant rollbacks.

Continuous delivery pipelines must guarantee zero dropped requests and instant rollback capabilities during active production releases.

1. Zero-Downtime Blue/Green Release Cycle

  • 1. Standby Build: Deploying the new release build to the idle standby port (e.g. Green :8083).
  • 2. Health Gate: Validating synthetic HTTP 200 health responses before initiating ingress routing updates.
  • 3. Atomic Nginx Reload: Modifying the upstream reverse proxy pointer and executing seamless worker reloads without dropping connections.
  • 4. Standby Convergence: Updating the warm standby slot asynchronously in the background.
