Measured Service
ОглавлениеMetering service usage allows a CSP to charge for the resources used. In a private cloud, this can allow an organization to charge each department based on their usage of the cloud. For a public cloud, it allows each customer to pay for the resources used or consumed. With a measured service, everyone pays their share of the costs.
The cloud is especially advantageous for organizations with peaks in their resource needs or cycles of usage. For example, a tax preparer uses more resources in the United States in the beginning of the year, peaking on April 15. Many industries have sales dates: Memorial Day, President's Day, Black Friday, Cyber Monday, Arbor Day, etc. Okay, maybe not Arbor Day. Resource needs peak at these times. A company can pay for the metered service for these peak times rather than maintaining the maximum resource level throughout the year. Maintaining the maximum resources in-house would be expensive and a waste of resources.
