Distributed WebSocket Architectures
Design and implement WebSocket applications in a distributed microservices environment.
Why Distribute WebSockets?
As your application grows, a single WebSocket server might not be enough to handle all user connections and message traffic.
Distributed WebSocket architectures allow you to scale your real-time applications by running multiple server instances. This helps with:
- Load balancing: Spreading connections across servers.
- High availability: No single point of failure.
- Microservices: Integrating real-time features into a distributed system.
The Stateful Challenge
A core challenge with WebSockets is their stateful nature. Each client maintains a persistent connection with a specific server instance.
If you have multiple server instances (Server A, Server B), and a client connected to Server A sends a message meant for a client connected to Server B, how does Server A know where to send it?
This problem requires a way for server instances to communicate with each other.
