A cloud service model that provisions application and database services as a platform for development of apps.

• A. Software as a Service (SaaS)
• B. Cloud service models
• C. Anything as a Service (XaaS)
• D. Platform as a Service (PaaS)

Answer: (D)

Platform as a Service provides a ready-to-use environment for building and deploying applications, including the runtime, development tools, and database services that developers need. The description—provisions application and database services as a platform for development of apps—fits this model because it emphasizes a development platform rather than delivering finished software or just raw infrastructure. SaaS would give you end-user software to use, not a development platform. XaaS is a broad umbrella term for anything-as-a-service. IaaS offers underlying compute, storage, and networking resources, not a full development platform with integrated app services.
