Zero Downtime Deployment

Zero Downtime Deployment is a release strategy that updates a running service without interrupting user-facing availability. It relies on patterns such as rolling updates, blue-green switchovers, or canary releases combined with health checks and load-balancer draining so that traffic only reaches instances ready to serve it. Achieving it requires backward-compatible changes, graceful connection shutdown, and idempotent operations across the transition.
