Which statement best describes the cloud service model IaaS in cloud computing?

• A. Provides virtualized infrastructure (compute, storage, and networking).
• B. Delivers a managed application platform (runtime and middleware).
• C. Offers fully built software accessed via the internet.
• D. Provides on-premises hardware management.

Answer: (A)

IaaS is about renting virtualized infrastructure over the internet. You’re given compute power, storage, and networking as scalable resources that you can configure and deploy on. The cloud provider handles the physical hardware and the virtualization layer, while you manage the operating system, middleware, runtime, data, and applications that run on that infrastructure. This aligns with describing IaaS as providing virtualized infrastructure (compute, storage, and networking). In contrast, a managed application platform corresponds to PaaS, fully built software accessed online is SaaS, and on-premises hardware management isn’t cloud-based.
