🔵🟢Blue-Green Deployment Strategy

Maintains two identical production environments (Blue and Green). One serves live traffic while the other is updated. Traffic is cut over instantly at the router.

🐤Canary Deployment Strategy

Rolls out new software to a tiny subset of users (e.g. 2%), monitors error rates and latency, and incrementally shifts remaining traffic if health checks pass.

🔄Rolling Deployment Strategy

Incrementally updates instances of an application by replacing old pods/servers with new ones one by one or in small batches.

🔁GitOps Synchronization & Reconciliation Loop
