In cloud computing, what does IaaS provide?

• A. Virtualized hardware such as VMs and storage
• B. Managed runtime for apps
• C. Software accessed via the cloud
• D. Networking as a service only

Answer: (A)

In IaaS you’re provided with virtualized hardware resources on demand. The cloud provider takes care of the physical infrastructure and the virtualization layer, while you configure and control the guest operating systems, storage, and networking you run on top of that. This means you can spin up virtual machines, allocate storage, and set up virtual networks as needed, paying only for what you use. That focus on raw compute and storage resources is why this model is described as IaaS. The other descriptions point to different service models: a managed runtime for applications corresponds to PaaS, and software accessed over the cloud describes SaaS. Networking as a service is a component you can use within cloud offerings but doesn’t define IaaS on its own.
