Microsoft Azure Fundamentals AZ-900 Practice Question

Platform as a Service (PaaS) is the correct choice. PaaS abstracts and manages the underlying infrastructure (like servers and networking) but still provides the ability to manage and scale application components and configure the runtime environment. This allows the development team to focus on the application and less on infrastructure management. Infrastructure as a Service (IaaS) would be incorrect because it requires managing the operating systems and underlying infrastructure. Software as a Service (SaaS) is incorrect as it provides ready-to-use software and does not allow for deploying and custom-configuring a complex, custom application. Serverless computing is less suitable because while it also abstracts infrastructure, it typically offers less control over the runtime environment configuration than PaaS, which was a key requirement.
