The acronym IaaS represents Infrastructure as a Service, a cloud service model that provides virtualized computing resources over the internet. IaaS allows businesses to rent IT infrastructure, including servers, storage, and networking, on a pay-as-you-go basis. This model offers flexibility, scalability, and cost-efficiency, enabling organizations to quickly adjust resources according to demand without investing in physical hardware. IaaS is ideal for businesses looking to reduce operational costs, enhance disaster recovery capabilities, and scale IT resources seamlessly to support their growth and operational needs.
