Scalable Database Architectures for Global Apps
Scalable Database Architectures for Global Apps Global apps face a simple challenge: users around the world expect fast, reliable access. The database must handle traffic spikes, protect data, and stay available during regional outages. The right architecture blends distribution, partitioning, and careful operations. Two core patterns help teams scale: multi-region replication and horizontal sharding. Replication places copies of data in nearby regions to lower latency for reads and to provide failover. Sharding splits data into smaller pieces so many servers can work in parallel. When used together, they reduce bottlenecks and support growing user bases. ...
