Which service model gives developers a platform to create and run their own applications, while the provider handles the underlying middleware and runtime?

• 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 cloud-based development and runtime environment where developers can create and deploy their own applications. The provider handles the underlying middleware, runtime, operating system, servers, and scaling, so you can focus on writing code and configuring the app rather than managing infrastructure. This setup contrasts with Software as a Service, which delivers ready-made software to users rather than a platform to build on. While XaaS is a broad umbrella for various as-a-service models, and “cloud service models” is a generic term, the described scenario specifically points to Platform as a Service.
