IaaS stands for which cloud service model?

• A. Infrastructure as a Service
• B. Integrated as a Service
• C. Infrastructure as a System
• D. Industrial as a Service

Answer: (A)

Infrastructure as a Service is a cloud service model that provides virtualized computing resources—such as servers, storage, and networking—over the internet. The provider manages the physical hardware, virtualization layer, and underlying infrastructure, while you manage the guest operating system, middleware, applications, and data. This setup lets you scale resources quickly and pay only for what you use, without buying and maintaining on‑prem hardware. The other terms listed aren’t standard cloud service models; the common ones are Infrastructure as a Service, Platform as a Service, and Software as a Service.
