Blue Green Deployments

By deploying to two (blue, green) separated but identically-configured infrastructure environments, teams can alternate their deployments so they serve from one while updating the other. This can be thought of as having a hot-standby during a release. It requires the ability to change traffic patterns and data consistency between the two platforms must also be considered.
