Description

Utility computing is the realization of "on-demand" computing which provides services for Cloud Computing, IT Departments and Mobile Networks. Services provided by utility computing providers are charged on actual elapsed CPU time used, simular to traditional electricity companies that charge in actual kilowatt used. Service level agreements between the utility computing provider and consumer for the service are mandatory for establishing reliable networks for business transactions. Without services level agreement contracts in place the availability of the utility computing resource cannot be guaranteed. Each utility service provider contributes as a paid service to the success of the overall transaction of the consumer. The utility computing company offers a list of services in form of a service catalog from which the consumers can purchase computing utilities. The service catalog contains services offered by the utility computing company.
