Microsoft Certified: Azure Fundamentals (AZ-900) Practice Exam

You want to deploy your own web application quickly without taking any responsibility for the Operating System, Web server, or system updates. What is the right solution for you?

1. DaaS

2. SaaS

3. PaaS

4. IaaS

The correct answer is: PaaS

The chosen answer is correct because Platform as a Service (PaaS) provides a cloud-based platform that enables developers to build, deploy, and manage applications without worrying about the underlying infrastructure, including the operating system and web server. PaaS abstracts these responsibilities, allowing you to focus on coding and deploying your application quickly. This model is particularly beneficial for scenarios where speed and efficiency are paramount, as it handles routine maintenance tasks like system updates and patches, which can greatly reduce the administrative burden on developers. In contrast, other options like DaaS (Desktop as a Service) and SaaS (Software as a Service) do not fit the scenario perfectly. DaaS focuses on providing virtual desktops, while SaaS delivers software applications over the internet without user control over the underlying infrastructure. IaaS (Infrastructure as a Service), meanwhile, requires users to manage the operating system and the underlying hardware, which is not aligned with your requirement to avoid responsibility for those components. Therefore, PaaS is indeed the most appropriate choice for quick deployment while minimizing operational responsibilities.
