'''Utility computing''' is the packaging of [[Computational resource|computing resources]], 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]]s 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. "On demand computing" should not to be confused with the term [[DEMAND computing]], which is an acronym describing a method of computing where devices use [[distributed applications]] (or dAPPs) to share processing and data storage capabilities in a network.

There was some initial skepticism about such a significant shift.<ref>{{citation | publisher=ZD Net | url=http://www.zdnet.com/news/on-demand-computing-what-are-the-odds/296135 | title=On-demand computing: What are the odds? | first= | last= | date=Nov 2002 | accessdate=Oct 2010}}</ref> However, the new model of computing caught on and eventually became mainstream.
