Predictive cost considerations

The ability for users to predict what cost they will incur for a particular cloud service.

Economies of Scale

The concept of __________ is the ability to do things more cheaply and efficiently by operating at a larger scale.

Capital Expenditure (Capex)

The spending of money on physical infrastructure up front, and then deducting that expense from your tax bill over time. It is an upfront cost which has a value that reduces over time.

Operational Expenditure

The spending of money on services or products now and being billed for them as you use them now. You can deduct this expense from your tax bill in the same year. There is no upfront cost, you pay for a service or product as you use it.
