Cloud servers
Your cloud server is a virtual server. It runs in a cloud computing environment, and it's a place where you’ll host your games’ matches and sessions.
Flex metal servers are basically bare-metal machines, but you can have them available in the same amount of time as cloud servers.
You’d usually need to order bare-metal servers in advance. So say you have a free weekend coming up. You can roughly estimate how many players will come in, and order in how many bare-metal servers you’ll think you’ll need. Whereas flex metal, you can do this in minutes.
It has the benefits of bare-metal, and can sometimes be cheaper than cloud. It can also be a good option if your server provider doesn’t offer cloud in specific regions, then flex metal is a good option to fall back on.

Peer-to-peer is when you designate one player as the host of a session, and the other players connect to their machine. Whereas client-side servers are external machines which hosts your game’s sessions.
