How Redis Cluster’s Decentralized Design Powers Billion‑Scale Traffic

When a single Redis instance can no longer hold the data volume or write load of e‑commerce workloads, the traditional master‑slave with Sentinel model reaches its limits, and Redis Cluster—by sharding data across 16,384 slots, using gossip‑based topology, and removing a central control plane—delivers horizontal scaling and fault‑tolerance for billions of requests, provided key design, hash tags, hot‑key mitigation, and client routing are applied.
