Blue-Green Deployment

PronunciationBLOO-GREEN dee-PLOY-ment

Definition

A deployment strategy that uses two identical production environments, where one is live while the other is updated, allowing for instant switching and easy rollbacks.

Where you hear it

In discussions about release management, CI/CD pipelines, and high-availability infrastructure.

Examples

  • We use Blue-Green Deployment to ensure zero downtime during our releases.
  • If the new version has a bug, we can quickly switch traffic back to the old environment.

Common mistake

Thinking that Blue-Green Deployment is the same as a staging environment; it is specifically about having two production-ready environments to facilitate seamless traffic switching.
