Which statement best describes the financial benefit of moving from on-premises servers to AWS?

A.Eliminates all costs

Cloud reduces upfront cost — it doesn't eliminate spending.

B.Converts large upfront capital expenses into variable operational expenses that scale with usage

Correct. Trade fixed capital expense for variable operating expense.

C.Guarantees lower cost for every workload

Poorly managed cloud can cost more — no guarantee.

D.Removes the need for any IT staff

Cloud shifts work, doesn't eliminate the need for engineers.

Why this answer

Cloud's core economic shift is CapEx → OpEx: no upfront hardware purchases; you pay for what you use and can scale down when demand falls. It doesn't guarantee universal savings — rightsizing still matters.
