Blue-Green

Adjective · Development

Definitions

  1. Describing a deployment strategy in which two nearly identical environments are maintained and traffic is switched from the old one to the new one when the release is ready. Blue-green releases reduce downtime and simplify rollback because the previous version remains intact until the cutover is accepted.

    In plain English: A release strategy that switches traffic between an old environment and a new one.

    Example: "They used a blue-green deployment so the new API fleet could warm up and pass checks before traffic moved over from the old stack."
