Blue-Green and Canary Deployments
Release new versions safely with zero downtime using blue-green and canary deployment strategies.
The Risk of Big-Bang Releases
Replacing all running instances at once is risky: a bad release takes down everyone immediately. Safer strategies roll out changes gradually or keep a tested fallback ready.
Blue-Green Overview
Blue-green runs two identical environments. Blue serves live traffic while you deploy and test the new version on green. When green is verified, you switch all traffic to it.
