Where Write Time Goes in Multi-Region Active-Active Databases

This article analyzes write latency in multi-region active-active databases like AWS Aurora DSQL, showing that local execution is only a small fraction of total latency while cross-region commit coordination dominates; it also examines optimistic concurrency control conflicts, hotspot contention, isolation level limitations, and criteria for when multi-region active-active truly benefits applications.

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.

How to Build True Multi‑Region Active‑Active Architecture with Bidirectional Sync

This article explains why true multi‑region active‑active requires data to be bidirectionally synchronized across three or more centers, and details a multi‑center disaster‑recovery architecture, distributed ID generation algorithms, CAP considerations, and techniques for achieving eventual consistency.
