Common use of IN UTILITY COMPUTING SYSTEMS Clause in Contracts

IN UTILITY COMPUTING SYSTEMS. As highlighted by ▇▇▇▇▇▇▇▇▇ (▇▇▇▇▇▇▇▇▇, 2008), there are many challenges involved in developing software for a million users to use as a service via a data center as compared to distributing software for a million users to run on their individual personal computers. Using SLAs to define service parameters that are re- quired by users, the service provider knows how users value their service requests, hence it provides feedback mechanisms to encourage and discourage service request submissions. In particular, utility models are essential to balance the supply and the demand of computing resources by selectively accept- ing and fulfilling limited service requests out of many competing service requests submitted. However, in the case of service providers making available a commercial offer to enable crucial business operations of companies, there are other critical QoS parameters to be considered in a service request, such as reliability and trust/security. In particular, QoS requirements cannot be static and need to be dy- namically updated over time due to continuing changes in business operations and operating environ- ments. In short, there should be greater importance on customers since they pay for accessing services. Therefore, the emphasis of this section is to describe SLA management for utility computing systems.
