Measuring Consumption
Measuring consumption is important in both private and public clouds. In
private clouds, consumption measurement supports departmental charge-backs.
In public clouds, consumption measurement supports both the pay in advance
(subscriptions) and pay afterwards (invoicing) models.
Because consumption requirements can change over time, initially allocated
resources may no longer match needs. Therefore, it is critical to meter resource
allocations on an ongoing basis so that invoices and reports reflect actual use.
Consumption measurement is also valuable for tracking the amount of resources
actually consumed (subset) versus the amount allocated. Comparing the subset
to the full allocation can enable greater efficiencies. This is especially important
for service providers in capacity planning. The system provides measures of
consumption for both customers and service providers.
