Blue/Green Deployments

Blue/green, sometimes referred to as red-black, deployment is a technique for releasing applications by shift traffic between two identical environments running differing versions of the application. Blue/green deployments help you minimize downtime during application updates mitigating risks surrounding downtime and rollback functionality. Blue/green deployments enable you to launch a new version (green) of your application alongside the old version (blue), and monitor and test the new version before you reroute traffic to it, rolling back on issue detection.
