Photon Unity Networking (PUN) is a Unity package for multiplayer games. Flexible matchmaking gets your players into rooms where objects can be synced over the network. RPCs, Custom Properties or "low level" Photon events are just some of the features. The fast and (optionally) reliable communication is done through dedicated Photon server(s), so clients don't need to connect one to one.

Colocation (colo) is a data center facility in which a business can rent space for servers and other computing hardware. Typically, a colo provides the building, cooling, power, bandwidth and physical security while the customer provides servers and storage.

 Managed Hosting :

Managed hosting is an IT provisioning model in which a service provider leases dedicated   servers and associated hardware to a single customer and manages those systems on the  customer's behalf.

 In managed hosting, customers can rent equipment such as dedicated server, storage and     network hardware; operating systems; and system software. The leased equipment serves only that single customer -- or "tenant" as customers are referred to  single-tenancy architecture. The customer usually has administrative access to the leased systems yet rarely uses it, instead opting to interact with the system through a web-based interface.
