Correct answer: D
Cloud computing models are fundamentally classified into three major layers based on what level of control and resources are managed by the cloud provider versus the end user.
Infrastructure-as-a-Service (IaaS): Gives you raw access to virtualization, storage, and networking. You manage the OS, middleware, runtime, and applications.
Platform-as-a-Service (PaaS): Provides the platform layer environment. The vendor manages the OS and runtime; you only manage your deployed applications and code.
Software-as-a-Service (SaaS): Provides a complete, ready-to-use software product. The vendor manages everything from the hardware up to the application interface.
Because System-as-a-Service (SyaaS) does not exist in standard computer science or cloud industry architectures, it is not a valid cloud service model.
