Which cloud service model provides a platform to deploy applications and may include a database engine, with the cloud provider handling the underlying infrastructure?

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

Answer: (B)

Platform as a Service provides a ready-to-use environment to deploy and run applications, while the cloud provider takes care of the underlying infrastructure. You get a platform that includes the runtime, development tools, and often services like a database engine, so you can focus on writing code and managing data without worrying about servers, storage, or the operating system. This differs from IaaS, where you manage the OS and software stack yourself; from SaaS, where you use a finished software product rather than deploying your own apps; and from DaaS, which is about delivering virtual desktops rather than app deployment.
