Which cloud service model provides a platform that developers can use to build and deploy applications without managing the underlying infrastructure?

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

Answer: (B)

Platform as a Service is a cloud model that provides a ready-to-use development and runtime environment. Developers can write, test, and deploy applications using the platform’s built-in tools, frameworks, databases, and services, while the provider handles the underlying infrastructure—servers, storage, networking, operating systems, and scaling. This lets you focus on coding and deployment rather than managing hardware or software layers. In contrast, infrastructure as a service gives you raw compute and storage resources without a built-in application runtime, software as a service delivers a complete application you use, and a DaaS offering typically focuses on virtual desktops (or data services), not a development platform.
