Microsoft Certified: Azure Fundamentals (AZ-900) Practice Exam

IaaS, or Infrastructure as a Service, is viewed as the most flexible category of cloud services because it provides the fundamental computing resources such as virtual machines, storage, and networks. Users have the ability to create, manage, and configure their own infrastructure environments, allowing for significant customization and control.

With IaaS, organizations can scale their resources up or down based on demand, deploy various operating systems, and install software applications as they see fit. This flexibility is particularly beneficial for businesses that require a varied and dynamic infrastructure setup, enabling them to build and manage applications without the overhead of managing physical hardware.

While other categories of cloud services, such as PaaS, SaaS, and DaaS, offer various levels of abstraction and manage different aspects of the technology stack, IaaS stands out in allowing users to tailor their infrastructure precisely to their needs, granting them flexibility that is essential for diverse workloads and development processes.
