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