'''Utility computing''', or '''The Computer Utility''', 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 [[Computationalsystem resource|computing resources]]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, [[computational resource]]sresources 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.
