Which cloud service model provides clients with servers, storage, and networks only?

The Infrastructure as a Service (IaaS) model is designed to provide clients with fundamental computing resources such as servers, storage options, and networking capabilities. In this model, users can rent virtualized hardware resources on demand, allowing them flexibility to scale up or down based on their needs without the physical limitations of traditional on-premises infrastructure.

IaaS is particularly beneficial for businesses looking to build and manage their own applications and environments without the overhead of physical hardware management. It allows users to maintain control over operating systems, applications, and data while the underlying infrastructure is managed by the cloud provider.

The other service models generally include additional layers of management and control; for example, Software as a Service (SaaS) delivers complete software applications over the internet while Platform as a Service (PaaS) provides a platform allowing clients to develop, run, and manage applications without worrying about the underlying infrastructure. Desktop as a Service (DaaS) focuses on delivering virtual desktops to users. Therefore, IaaS is distinguished by its offering of basic infrastructure components.
