Blue-Green Deployment and Canary Releases

Blue-Green Deployment and Canary Releases are modern strategies for safe software updates.  

Blue-Green Deployment uses two environments: Blue (current) and Green (new version). Traffic initially flows to Blue. When Green is ready, all traffic switches to it, allowing quick rollback if needed. This minimizes downtime but requires duplicate infrastructure.  

Canary Releases roll out updates to a small user group first. If successful, the rollout gradually expands, reducing risk by limiting exposure to potential issues.  

Both methods ensure smoother deployments, better control, and enhanced reliability.
