Every day more data was received than the computers at the university could process, so volunteers were asked to donate idle processing time on their home computers.

As more business applications are moved to the Web, portals give users access to central databases with a Web browser or cell phone eliminating the need to purchase and install special purpose desktop software. Self-service applications are instrumental in reducing operating costs by eliminating many administrative processes, reducing personnel costs, and providing access on demand 24 hours a day.
In addition to applications such as store fronts, many traditionally back-office applications can also be made self-service, including travel, payroll, and human resources. 6 The g in Oracle Database 10g—The Grid Consolidation sets the stage for the implementation of grid computing.
