Which cloud service model focuses on providing a platform that includes development tools and runtime environments for building and deploying applications, while users do not manage the underlying infrastructure?

• A. CaaS
• B. PaaS
• C. IaaS
• D. SaaS

Answer: (B)

Providing a platform with built-in development tools and runtime environments while the user doesn’t manage the underlying infrastructure describes a platform as a service. This model gives you a ready-to-use environment for coding, building, testing, and deploying applications, with the cloud provider handling servers, storage, networking, the operating system, patching, and scaling. You focus on your code and configuration rather than managing the hardware or OS. For example, services like Google App Engine, Heroku, or Azure App Service let you deploy apps directly into a managed platform. In contrast, IaaS places more of the stack under your control (you manage the OS and middleware), SaaS delivers finished software as a service, and CaaS centers on container orchestration rather than a full application development platform.
