utility computing
(redirected from Computing on demand)

   Also found in: Wikipedia 0.06 sec.

(1) Pay-per-usage processing provided by a service organization that uses its own computers and facilities. Customers access the computers via a private network or over the Internet and are charged according to how much computing time they use, such as CPU seconds, minutes or hours. Also called "on demand computing" and "cloud computing."

If the service organization also includes the software, the organization is called an "application service provider" (ASP), and the products fall under the umbrella of "software-as-a-service" (SaaS). See ASP and SaaS.

(2) Another term for peer-to-peer computing or grid computing. See peer-to-peer computing.
