How do I Create a dedicated server for my game?

Hello guys. Would someone recommend me links or a post where I can learn how to create a server for my game. My game would be like Agar.io or slither.io where people play a game against other people online. Is it possible to do this with construct 3 games or the only multiplayer way is peer-to-peer.

Thank you very much

I think you should see a Photon Multiplayer addon and his tutorials.
