Which service model provides virtualized infrastructure such as virtual machines and storage?

• A. PaaS
• B. SaaS
• C. IaaS
• D. Public Cloud

Answer: (C)

Virtualized infrastructure is provided by Infrastructure as a Service (IaaS). In this model, the cloud provider delivers computing resources over the internet in the form of virtual machines, storage, and networking. You can provision and manage these resources as needed, installing operating systems and applications while the provider takes care of the physical hardware and the virtualization layer. This differs from Platform as a Service, which gives you a development platform and runtime components to build and deploy apps without managing the underlying server infrastructure, and Software as a Service, which delivers ready-to-use software applications. Public Cloud describes where the resources are hosted (shared, provider-managed data centers) rather than the service type itself. So, the ability to spin up virtual machines and storage is the hallmark of IaaS.
