Blue-Green Deployment Switcher

Software componentInfrastructureInfrastructurearc:BlueGreenDeploymentSwitcher

A rollout controller that runs the stable and new versions as parallel full environments and switches all traffic between them at once, keeping the old environment ready for instant failback.

Responsibility. Performs instantaneous whole-traffic cutover and failback between versions.

Also known as: Blue-green deployment, Blue-Green Deployment Controller

Variant of Rollout Manager abstract

When to choose. Choose when validation completes before cutover and instant switch-over with instant failback to a fully running previous version is required.
