# Peer-to-peer architecture

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 host your game’s sessions.

## Why offer peer-to-peer servers?

Peer-to-peer is a great option for smaller, more cooperative games. If you have a turn-based strategy, or even world-builder game, then it probably doesn’t matter if one player has the advantage. It lets your players have their own private server, and can actually be faster than rerouting through a client-server. The bonus, offering peer-to-peer can save your company costs on renting client-side servers.

But the big downside, which people usually forget about, is if the host leaves, you need to migrate the session over to one of the other players. And that’s not always possible or can cause a huge delay. Also, if the player has bad internet, or a weak machine, then that affects the gameplay for everyone.

## You’ll usually also need client-server architecture

It’s rare for games to only offer peer-to-peer servers. It’s a great feature to have, but your players may not always want to host the game themselves. And if you have an FPS game with a lot of players, then you definitely don’t just want to rely on peer-to-peer.

Building a multiplayer game? Gameye hosts dedicated game servers: ship your server as a Docker container and start one per match with a single API call, in a region near your players.
