Infrastructure as a Service (IaaS) is a cloud computing model that provides virtualized computing resources over the internet, such as servers, storage, and networking. It allows businesses to rent IT infrastructure on a pay-as-you-go basis, eliminating the need for physical hardware and reducing capital expenditures. IaaS offers flexibility, scalability, and easy management, enabling organizations to scale their infrastructure as needed without worrying about maintenance or upgrades. Examples of Infrastructure as a Service (IaaS) providers include Amazon Web Services (AWS), Microsoft Azure, Google Cloud Platform, and IBM Cloud, all offering scalable virtualized computing resources for businesses.
