Final answer:
Infrastructure as a Service (IaaS) is the cloud computing service providing raw compute, storage, and network, and is most similar to physical data centers. It allows the renting of virtual machines and the managing of networks and storage capacities, while the physical infrastructure is handled by the service providers.
Step-by-step explanation:
The type of cloud computing service that provides raw compute, storage, and network, organized in ways that are familiar from physical data centers, is called Infrastructure as a Service (IaaS). IaaS delivers fundamental compute, network, and storage resources to consumers on-demand, over the internet, and on a pay-as-you-go basis. Users of IaaS can rent virtual machines, use storage capacity, and configure networking, among other services, while the provider manages the physical infrastructure.
Unlike Platform as a Service (PaaS), which offers a development environment, and Software as a Service (SaaS), which is focused on delivering software applications over the internet, IaaS provides the virtualized infrastructure for running all forms of software, including operating systems and applications.
