Microsoft Azure Fundamentals AZ-900 Practice Question

Infrastructure as a Service (IaaS) provides virtualized computing resources over the internet, allowing organizations complete control over their virtual machines, including the operating systems, applications, and network configurations. This matches the organization's need for full control while offloading the underlying hardware maintenance to the cloud provider.

Software as a Service (SaaS) delivers fully managed applications over the internet, with minimal control for the customer over the underlying infrastructure or application code. Platform as a Service (PaaS) provides a platform allowing customers to develop, run, and manage applications without dealing with infrastructure maintenance, but with less control over the operating system compared to IaaS. Function as a Service (FaaS), or serverless computing, allows customers to execute code in response to events without managing servers, which doesn't meet the requirement for full control over virtual machines.
