{{short description|Service provisioning model}}

'''Utility computing''', or '''Thecomputer Computer Utilityutility''', is a service provisioning model in which a service provider makes computing resources and infrastructure management available to the customer as needed, and charges them for specific usage rather than a flat rate. Like other types of on-demand computing (such as grid computing), the utility model seeks to maximize the efficient use of resources and/or minimize associated costs. Utility is the packaging of [[system resource]]s, such as computation, storage and services, as a metered service. This model has the advantage of a low or no initial cost to acquire computer resources; instead, resources are essentially rented.

This repackaging of computing services became the foundation of the shift to "[[Code on demand|on demand]]" computing, [[software as a service]] and [[cloud computing]] models that further propagated the idea of computing, application and network as a service.

The term "[[grid computing]]" is often used to describe a particular form of distributed computing, where the supporting nodes are geographically distributed or cross [[administrative ___domain]]s. To provide utility computing services, a company can "bundle" the resources of members of the public for sale, who might be paid with a portion of the revenue from clients.

One model, common among [[volunteer computing]] applications, is for a central server to dispense tasks to participating nodes, on the behest of approved end-users (in the commercial case, the paying customers). Another model, sometimes called the [[Virtualvirtual Organizationorganization (Gridgrid computing)|Virtualvirtual Organizationorganization]] (VO),{{Citation needed|date=June 2007}} is more decentralized, with organizations buying and selling [[Computational resource|computing resources]] as needed or as they go idle.

The definition of "utility computing" is sometimes extended to specialized tasks, such as [[web service]]s.
