Server architecture for an online Android game?

Question

Android

Good day to everyone, I decided to try my hand at game development. I would like to know approximately the server architecture of the mobile toy AFK Arena, because. I'm going to do something along these lines. And, of course, I would like to know how the server part is properly organized in such games. Because I don't know much about gamedev and I'm just starting my way. I want to thank in advance all those who answer the question. :)
