Cloud computing is a new computing paradigm that, just as electricity was firstly generated at home and evolved to be supplied from a few utility providers, aims to transform computing into an utility. It is being forecasted that more and more users will rent computing as a service, moving the processing power and storage to centralized infrastructures rather than located in client hardware. Consumers are not used to renting computing capacity. The question of how to measure performance is already a major issue for cloud computing customers.
