I have been learning networking for about 4 months. Wrote a single standalone Multiplayer server and succeeded with authoritative approach. Now I want to extend it by splitting the single server into clusters to allow even more players to log in to avoid latency issues. Now I have protyped the Loadbalancing server and its running pretty good so far.

This is my architecture, I have a master server which acts as a proxy, every sub servers(chat, login, game) connect to the master server as well as all the clients. when a client connects,

Client Request: Send Request -> MS(Master) -> Decides which SS(SubServer) to forward to -> Forwards Request to SS -> SS -> Analyze Message -> Send Response to MS -> Decides which Client to forward to -> Forwards Response to Client

Well, it looks like its going through lots of stages. it takes double the time to process the message than a single server approach. i feel like my model isnt the best or i may be wrong. is there any better model or the one they use in professional games? I still want a Master-SubServer approach.

I just want to clarify that I'm going in the right direction before writing all my codes. Thanks for any answer :)
