Which cloud service model gives customers a hosting platform to build and deploy apps?

• A. IaaS
• B. SaaS
• C. Cloud Concepts
• D. Platform as a Service (PaaS)

Answer: (D)

The concept tested is which cloud model provides a hosting platform with built-in tools and environments for building and deploying applications. Platform as a Service fits this exactly because it supplies the runtime, development tools, databases, and deployment infrastructure as an integrated platform. You focus on writing and deploying your code while the provider handles the underlying servers, operating system, and middleware, along with scaling and maintenance. In contrast, infrastructure as a service gives you raw computing resources (virtual machines, storage, networks) that you configure and manage, including the OS and runtime. Software as a Service, on the other hand, delivers a complete application you just use—no building or deploying apps yourself. “Cloud Concepts” is a broad term, not a specific service model.
