What's the difference between Master Server and Dedicated Server?

Hey I am confused, I don’t see the difference between a master server and a dedicated server. What about steam OnlineSubSystem, is it a dedicated server?

So the dedicated server is connected to the master server and send to it all the active game sessions(servers).


The Steam master server is a server that lets you find dedicated servers. It is not a game server itself.

A dedicated server is a game server that hosts your game. It registers itself with the master server so that players can find your server.

Yes, exactly.

ok thank you very much!
