Which cloud service model provides virtualized infrastructure resources such as compute, storage, and networking without bundling development platforms?

• A. IaaS
• B. PaaS
• C. SaaS
• D. XaaS

Answer: (A)

The main concept here is distinguishing infrastructure-level cloud services from platform and software solutions. IaaS provides virtualized compute, storage, and networking resources without bundling a development platform or runtime. You’re responsible for installing and managing the operating system, middleware, and applications, while the provider handles the underlying hardware, virtualization, and network connectivity. This separation is what sets IaaS apart from PaaS, which includes a development platform and tools; SaaS, which delivers ready-made software applications; and XaaS, a broad umbrella for any service-as-a-service offering. So the option that describes infrastructure-only resources is the correct one.
