Which cloud solution provides only hardware and network resources to make up a cloud environment?

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

Answer: (D)

Cloud service models define who manages what across the stack. The model that provides only hardware and network resources is Infrastructure as a Service. In this setup, the provider supplies the physical hardware, virtualization, storage, and networking, while you provision and manage the virtual machines, install and maintain the operating system, middleware, runtime, and applications, and handle data and security. You’re responsible for building and operating the software environment on top of the raw resources. SaaS delivers a complete, ready-to-use application managed by the provider. PaaS offers a managed platform with runtimes and development tools, where you focus on your apps but not the underlying OS. CaaS centers on container orchestration and runtime environments, adding more management layers than raw hardware.
