The Hidden Trap: Why Round-Robin Fails WebSockets
In the world of web architecture, the load balancer is the unsung hero. For standard, stateless HTTP traffic, a simple Round-Robin strategy is often the gold standard. It’s predictable, easy to implement, and keeps your server utilization roughly equal.
However, when you shift your architecture to support real-time features using WebSockets, the rules of the game change. Defaulting to Round-Robin for WebSocket load balancing is one of the fastest ways to crash your production real-time system.
Why the Math Breaks Down
To understand the failure, we must look at the fundamental difference between HTTP and WebSockets.
