The term "Infrastructure as a Service" (IaaS) refers to a cloud service model that delivers virtualized computing resources over the internet. In this model, users can rent IT infrastructure such as servers, storage, and networking components, rather than owning physical hardware. This flexibility allows organizations to scale their resources up or down based on their needs and provides significant cost savings, as they only pay for what they use and avoid the capital expenses associated with purchasing and maintaining physical hardware.

IaaS is a crucial component of cloud computing because it enables businesses to host applications, store data, and manage backups without the constraints of managing on-premises hardware. It allows developers and IT teams to focus on deploying and managing applications rather than worrying about the physical infrastructure that supports them.

This choice accurately captures the essence of IaaS, distinguishing it from other concepts or methods that are not related to the cloud infrastructure model.
