Infrastructure as a Service

Definition

Infrastructure as a Service (IaaS) is a cloud computing model that provides virtualized computing resources over the internet. This service allows organizations to access essential hardware components, such as servers, storage, and networking, without needing to invest in physical infrastructure. By leveraging IaaS, businesses can efficiently manage resources on-demand and scale their operations as needed while reducing costs associated with traditional IT management.
