Which cloud service model primarily provides virtual machines, storage, and networks?

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

Answer: (A)

Understanding cloud service models, the one that focuses on infrastructure resources—virtual machines, storage, and networking—is IaaS. This model provides the fundamental building blocks for computing in the cloud, letting you deploy and manage operating systems, applications, and data on top of the provider’s infrastructure. The cloud provider handles the underlying hardware, virtualization, and network, while you control the software stack and configurations. SaaS, by contrast, delivers ready-to-use software over the internet, with minimal management by you. PaaS offers a development platform and runtime so you can build and deploy apps without worrying about the underlying infrastructure. DaaS centers on providing a virtual desktop environment to end users rather than the core infrastructure.
