Building Resilient Real-Time Systems with WebSockets and Redis Pub/Sub

Originally published on tamiz.pro.

Building real-time systems that can withstand failures, scale efficiently, and deliver messages with low latency is a critical challenge in modern software architecture. This deep-dive explores how to combine WebSockets for persistent client-server communication with Redis Pub/Sub for a resilient, scalable, and performant message broadcasting layer.
