!!! Overview
[{$pagename}] is a [Release Management] option where traffic between two identical environments that are running different [versions] of the same [application]. 


The Blue environment represents the current [application] [version] running in the [Production tier] traffic. In parallel, the Green environment is staged running a different [version] of your [application]. After the green environment is ready and tested, [Production tier] [network traffic] is redirected from blue to green. 

If any [Anomalies|Anomaly] are identified, recovery is performed by reverting traffic back to the blue environment. (Green-Blue Deployment)

[{$pagename}]s, sometimes called, Rolling updates, allow the following actions:
* Promote an [application] from one [Deployment tier] to another (via container image updates)
* Rollback to previous [versions]
* [Continuous integration] and [Continuous Delivery] of [applications] with zero downtime
