How do I implement blue/green deployments for Immutable infrastructure?

Implementing blue/green deployments for immutable infrastructure is an effective strategy to reduce downtime and ensure seamless application updates. This approach involves maintaining two identical environments (blue and green) where you can deploy new versions of your application without disruption.

Steps to Implement Blue/Green Deployments

  1. Prepare two identical environments: Blue (current production) and Green (new version).
  2. Deploy the new version of your application to the Green environment.
  3. Run tests on the Green environment to ensure everything functions correctly.
  4. Switch traffic from Blue to Green environment seamlessly.
  5. If any issues arise, rollback traffic back to Blue.
