Microsoft 365 Fundamentals MS-900 Practice Question

They should use Platform as a Service (PaaS) because it offers an environment equipped with all the resources needed to develop, test, and deploy applications without the complexity of managing the underlying infrastructure. Infrastructure as a Service (IaaS) provides virtualized computing resources but requires the user to manage operating systems, middleware, and applications. Software as a Service (SaaS) delivers fully developed applications over the internet, which doesn't meet the requirement of building custom applications. Function as a Service (FaaS) allows users to execute code in response to events without managing servers, but it's more suitable for event-driven, serverless architectures rather than developing complete custom applications.
