Name the model which allows a user to create applications without dealing with the underlying infrastructure management?

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

Answer: (B)

The model that allows a user to create applications without having to manage the underlying infrastructure is Platform as a Service, or PaaS. PaaS provides a cloud environment that includes a range of services like development tools, databases, and application hosting, allowing developers to focus on writing code and building applications rather than worrying about the infrastructure such as servers, storage, and networking. This abstraction simplifies the development process and accelerates application deployment because users can leverage the platform’s built-in capabilities and scalability without the overhead of managing the hardware or software stack. In contrast, Infrastructure as a Service (IaaS) involves managing virtualized computing resources over the internet, meaning users must handle aspects of the infrastructure, including operating systems and middleware. Software as a Service (SaaS) delivers software applications over the internet without needing user management of the underlying infrastructure but does not provide a platform for building applications. Function as a Service (FaaS) is a serverless computing model that allows developers to run individual functions in response to events but still requires some understanding of the underlying environment for deployment and execution. PaaS distinctly fills the gap of enabling application creation with minimal infrastructure management.
