Hi everyone,
I’m planning to create a browser-based chat system using J2EE for the backend. I want it to work similarly to Gmail to ensure that performance remains stable even with heavy user loads. Could anyone recommend an architectural approach that supports high scalability and optimal performance?
Thanks in advance.
In my experience building similar systems, combining asynchronous processing with flexible connection management has been key. I ended up using servlets with a non-blocking I/O model along with WebSocket protocols for real-time updates. Integrating an event-driven mechanism with a reliable message queue provided an effective means to distribute the load and process messages asynchronously. Additionally, employing caching on the application layer helped reduce database pressure during peak times. This approach has proven to be both scalable and manageable over time, even as user traffic grew substantially.
