Solutions Overview

Blue-green deployment is a release management technique that reduces risk and minimizes downtime. It uses two production environments, known as Blue and Green, to provide reliable testing, continuous no-outage upgrades, and instant rollbacks.

The old version can be called the blue environment while the new version can be known as the green environment. Once production traffic is fully transferred from blue to green, blue can standby in case of rollback or pulled from production and updated to become the template upon which the next update is made.
