Classifying the provision of cloud services and the limit of the cloud service provider's responsibility as software, platform, infrastructure, and so on.

Classifying the provision of cloud services and the limit of the cloud service provider's responsibility as software, platform, infrastructure, and so on.

• A. Cloud service models
• B. Anything as a Service (XaaS)
• C. Cloud computing
• D. Cloud service providers (CSPs)

Answer: (A)

This question is about how cloud services are organized by who is responsible for which parts of the stack. The way services are provisioned and where the provider’s responsibility ends and yours begins is captured by cloud service models. These models—such as infrastructure as a service, platform as a service, and software as a service—map out who handles the underlying hardware, the virtualization, the operating system, the runtime, and the applications. That boundary is exactly what the question is asking about: how the service is provided and where the provider’s liability stops. XaaS is a broader umbrella term for anything-as-a-service, not the specific way responsibilities are divided. Cloud computing is the overall concept that encompasses all of these, and CSPs are the providers themselves, not the categorization for responsibility. So the best fit is cloud service models.
