Utility Computing
Utility computing is the packaging of computing resources (on-demand software, SaaS), such as computation and storage, as a metered service similar to a traditional public utility (such as electricity, water, natural gas, or telephone network).  This system has the advantage of a low or no initial cost to acquire hardware; instead, computational resources are essentially rented.  Customers with very large computations or a sudden peak in demand can also avoid the delays that would result from physically acquiring and assembling a large number of computers.

Conventional Internet web hosting services have the capability to quickly arrange for the rental of individual servers, for example to provision a bank of web servers to accommodate a sudden surge in traffic to a web site.

"Utility computing" has usually envisioned some form of virtualization so that the amount of storage or computing power available is considerably larger than that of a single time-sharing computer.  Multiple servers are used on the "back end" to make this possible.  These might be a dedicated computer cluster specifically built for the purpose of being rented out, or even an under-utilized supercomputer.  The technique of running a single calculation on multiple computers is known as distributed computing.

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.

The definition of "utility computing" is sometimes extended to specialized tasks, such as web services (web hosting, win 32 hosting).

Wizmo Inc, a SaaS (Software as a Service) solution provider.  SaaS is a model of software deployment where an application is hosted as a service provided to customers across the Internet.  By eliminating the need to install and run the application on the customer's own computer, SaaS alleviates the customer's burden of software maintenance, ongoing operation, and support.  Using SaaS also can reduce the up-front expense of software purchases, through less costly, on-demand pricing.  From the software vendor's standpoint, SaaS has the attraction of providing stronger protection of its intellectual property and establishing an ongoing revenue stream.
