How does online cross-play work on games?

Question

I understand the principle but specifically how does it work?

Is it about servers? Do all consoles have the ability to support cross-play, and its just a matter of the developers working to include it in a game? What are the challenges involved in cross-play?

Answer 1

All internet connected devices supports cross-play. What needs to support cross-play for it to work in games is the game itself and the supporting servers. So long as the game is programmed to be able to communicate with all platforms at once, cross-play is possible.
