Zero Downtime Isn't Accidental: Deep Dive into Kubernetes Smooth Deployments from Theory to Production

Zero‑downtime releases require coordinated control‑plane and data‑plane actions—proper RollingUpdate settings, pod lifecycle handling, service‑mesh draining, pre‑warm of dependencies, capacity safeguards, and automated monitoring/rollback—otherwise brief spikes of 502/503 errors and duplicate consumption will appear.
