Which cloud service model provides hardware and software tools needed for application development via the Internet, hosted by the provider?

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

Answer: (B)

Platform as a Service provides an on-demand development platform in the cloud. The provider hosts the hardware and the full software stack needed to build, test, and deploy applications—runtime, frameworks, libraries, databases, and embedded development tools—so you can focus on coding rather than managing servers. This setup gives you a ready-to-use environment, scalable resources, and streamlined deployment, with the provider handling the underlying infrastructure maintenance. In contrast, infrastructure as a service offers raw compute and storage resources with you managing the OS and middleware; software as a service delivers finished applications you use directly; and desktop as a service centers on delivering virtual desktops rather than development tools.
