Cloud computing services are consumed using an on-demand model. Service providers, therefore, meter and monitor the consumption of every resource by every user. Every resource, in turn, uses specific metrics and measurement units to bill users. Most organizations do not measure IT usage in this way. Neither do they typically place resource measurement sensors across their IT platform. IT is usually seen as a shared cost center with only the total cost and total capacity requirements tracked.
