Microsoft Azure Fundamentals AZ-900 Practice Question

Platform as a Service (PaaS) provides a cloud-based environment where developers can build and deploy applications without managing the underlying infrastructure like servers and operating systems. The cloud provider manages the platform, including middleware and development tools, allowing developers to focus on their applications. Infrastructure as a Service (IaaS) requires users to manage operating systems and applications themselves. Software as a Service (SaaS) delivers fully developed applications over the internet for end-users. Function as a Service (FaaS) allows developers to execute code in response to events without managing servers but does not provide the comprehensive development platform that PaaS offers.
