Which service model does the term "IaaS" refer to?

The term "IaaS" stands for "Infrastructure as a Service." This service model provides virtualized computing resources over the internet. IaaS enables users to rent IT infrastructure, such as servers and storage, rather than investing in physical hardware.

With IaaS, organizations can quickly scale their infrastructure as needed, accommodating spikes in demand without the need for significant upfront capital expenditures. It offers a flexible and efficient way to manage computing resources, as users can adjust their usage based on current needs.

IaaS stands out from other service models like Software as a Service, which delivers software applications over the internet, or Platform as a Service, which provides a platform allowing developers to build and deploy their applications without hosting infrastructure management. Understanding the distinction between these models is essential for leveraging cloud computing effectively and knowing which service model best fits the needs of an organization.
