Microsoft Azure Fundamentals AZ-900 Practice Question

IaaS (Infrastructure as a Service) provides essential compute, network and storage resources, allowing customers to install and manage operating systems and applications themselves. This gives them greater control over their environment compared to other cloud service models. In contrast, PaaS (Platform as a Service) offers a managed environment for application development without the need to manage underlying infrastructure. SaaS (Software as a Service) delivers fully managed applications to end-users, and FaaS (Function as a Service) enables developers to execute code in response to events without managing server infrastructure.
