Where to make calculations for an online game?

Question

Game development

I once heard that this requires a VPS, I already wanted to go buy it, but I read that not only it can turn out to be. But what else is possible, I still do not understand.

Answer 1

I read that not only it can be

• you can rent a dedicated server from a hoster (dedicated iron, not virtual)
  
• you can buy your own hardware and put it on colocation in someone else's datacenter
  
• you can completely organize your server room (your own premises, your own hardware, your own system administrator)
  
• it is possible to make an online game without a server, such as p2p, with inherent limitations
  
• you can write a game server on web technologies and use shared hosting
