Solved How big servers work?

Hi, I want to know how big servers (like CubeCraftGames) work.
How do they do that if a player selects another lobby the player stays connected and is not disconnected? Are the lobby multiple maps on one server?

Please even if you just have a suggestion answer this thread!
My last thread did not even get an answer...
Thanks for Reply (;

 

I think some proxy.... hive does this too except they put up a loading nether screen..

 

Ok ,thanks for your reply! Do you know how can i get or create a proxy for pocketmine?

 

There are proxies like proxprox amd synapse but they are nothing like those big servers

 

Nemisys works well. However it depends SynapsePM plugin on each server.
