Scale Your Games World-Wide

All applications you develop with our suite of Photon products will run in our Photon Cloud. Here we take care of service hosting, operations and scaling. You can fully concentrate on building your game or app!

Photon

Photon Shared Mode -
Unique & Cost-Effective

In a nutshell the Photon Enterprise Cloud is like our well established public Photon Cloud and adds the following features: Runs on dedicated servers, provides guaranteed service levels (SLAs) and high priority support. Another big plus: You can run your own authoritative server logic via Plug-ins. Typical Photon Enterprise Cloud scenarios are apps with 10,000 concurrent users or more, bigger game projects that need authoritative server logic or companies whose compliance policies restrict them to dedicated resources.

Custom Plugins -
Server Authority in Our Cloud

All Photon Cloud products are based on a client to server architecture, the most stable solution for multiplayer games! In peer-to-peer architectures clients often cannot connect due to NAT punch-through issues. This problem is even worse in mobile networks. With the Photon Cloud your games will always connect.
Our operations team monitors servers 24/7 and can scale up required resources at any time. Whether your game needs capacity for hundreds or for hundreds of thousands of concurrent users: we scale it to your demands.

PHOTON CLOUD REGIONS

Low-Latency Gaming for Your Players

Low latency is an essential requirement in realtime multiplayer games. For this reason Photon Cloud is hosted in all major world regions to provide your players with a minimum latency.
Games that depend on low latency, like FPS or RTS game types, connect the players to the nearest region. Games that are able to handle higher latency, like turnbased game types, can connect all players to the same region.

See here for available regions and setup instructions.

Code Examples

Photon Unity Networking (PUN) re-implements and enhances the features of Unity’s built-in networking. Under the hood, it uses Photon’s features to communicate and match players. The API is very similar to Unity’s. Developers with prior networking experience in Unity will feel at home immediately. An automatic converter assists you porting existing Unity multiplayer projects.

Connect


                            PhotonNetwork.ConnectUsingSettings("1.0");
                            

Connecting our loadbalanced servers is as easy. You can use the passed in string to distinguish between versions or use it to group clients. Connecting our loadbalanced servers is as easy. You can use the passed in string to distinguish between versions or use it to group clients.

Join a Game


                            PhotonNetwork.JoinRandomRoom("1.0");
                            

To join any existing game (often referred to as room as well) that is all it takes. Filters for max amount of players and game specific criteria are optionally passed in.

Create a Game


                            public void OnConnectedToMaster()
                            {
                                PhotonNetwork.CreateRoom("Room42", true, true, 4);
                            }
                            

Set up a new room using CreateRoom. Hand it over the room’s name, the room’s ability to be found by others, the option for others to join in and the max player count.

Start Multiplayer


                            PhotonNetwork.RaiseEvent( (byte) eventCode,
                                (object) eventContent,
                                (bool) sendReliable
                            );
                            

Exchange in-game-data, set remote object properties e.a. sending them by RPC.
