Which cloud service model offers development tools and deployment platforms on demand, allowing developers to deploy and configure applications without managing the underlying infrastructure?

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

Answer: (B)

Platform as a Service provides development tools and deployment platforms on demand, letting developers deploy and configure applications without handling the underlying infrastructure. It offers a ready-made runtime environment, middleware, and deployment capabilities so you can focus on code and configuration while the provider manages servers, scaling, and patching. In contrast, IaaS delivers virtualized hardware resources and requires you to manage the operating system and software stack; SaaS offers complete software applications to users with no deployment to manage; IDaaS focuses on identity management services rather than app deployment platforms.
