Which service model provides raw infrastructure resources such as virtual machines and storage to customers?

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

Answer: (A)

Providing raw infrastructure resources such as virtual machines and storage is the hallmark of IaaS. In this model, you rent the basic building blocks—compute, storage, and networking—and you handle the operating system, applications, and data yourself, while the provider takes care of the underlying hardware, virtualization, and data center security. This setup gives you maximum control and flexibility to configure and scale as needed. In contrast, PaaS offers a managed platform with runtime and development tools so you focus on building apps; SaaS delivers ready-to-use software managed by the provider; and DBaaS provides database services with management abstracted away, but not the broader infrastructure. So the model that provides raw infrastructure resources is IaaS.
