Shared Nothing Architecture

Definitions

1. A distributed system design in which each node has its own private CPU, memory, and storage with no shared resources between nodes, eliminating contention and enabling near-linear horizontal scaling — used by systems like Citus, CockroachDB, and many microservice deployments.

   In plain English: A system design where each server is completely independent with its own data and memory, so adding more servers scales easily.

   Example: "Our shared-nothing architecture means we scale by adding nodes — there's no central database or shared disk to bottleneck."
