Which cloud service model provides consumers with access to infrastructure resources such as virtual machines, storage, and networks, but requires them to manage the operating system and applications?
- AFunction as a Service (FaaS)
- BSoftware as a Service (SaaS)
- CPlatform as a Service (PaaS)
- DInfrastructure as a Service (IaaS)
Show answer & explanationAnswer & explanation
Correct answer: D. Infrastructure as a Service (IaaS)
IaaS provides the foundational computing resources, giving users control over operating systems, applications, and middleware. The cloud provider manages the underlying hardware and virtualization.
Why the other options are wrong
- A. FaaS is a serverless execution model where the cloud provider manages servers and users deploy code functions.
- B. SaaS provides a complete, ready-to-use application, with users having no control over the underlying infrastructure or platform.
- C. PaaS provides a development and deployment environment, abstracting away the underlying infrastructure.

- Provides fundamental computing resources.
- Customer has control over OS, applications, and data.
- Cloud provider manages virtualization, servers, storage, and networking hardware.
Memory trick: Remember 'I' for Infrastructure, 'P' for Platform, 'S' for Software.
