Unitized Deployment: Turning a Shared Cluster into N Isolated, Self‑Contained Units for 10M+ QPS

The article explains why a monolithic shared‑cluster architecture hits a hard limit at the central database, introduces unitized deployment with RZone/GZone/CZone models and routing correction, and evaluates the resulting unlimited horizontal scaling, reduced blast radius, multi‑region active‑active capability against the high refactoring, data‑sync, operational and data‑correctness costs.
