When Server A receives an update, it sends a message to the Hub. The Hub then broadcasts that message only to the specific clients who need to see it, reducing unnecessary bandwidth. 3. Security: The "Gatekeeper" Role
Building a server-side hub is about moving from "direct communication" to "orchestrated communication." By centralizing your logic, you make your entire ecosystem easier to monitor, secure, and scale. How To Make A Serverside Hub Part 2/2
Use Socket.io (Node.js) or SignalR (.NET). This creates a "persistent pipe" between the hub and the users. When Server A receives an update, it sends
If you are using WebSockets, ensure your load balancer supports "sticky sessions" so a user stays connected to the same hub instance during their session. Conclusion Security: The "Gatekeeper" Role Building a server-side hub
Run multiple instances of your hub behind a Load Balancer .
Start by implementing a simple Redis cache to see how much it improves your hub’s response times!
