IaaS — Meaning and details

Infrastructure as a Service

Infrastructure as a Service (IaaS) is a form of cloud computing that provides virtualized computing resources over the internet. IaaS is one of the three main categories of cloud services, alongside Software as a Service (SaaS) and Platform as a Service (PaaS). In an IaaS model, a cloud provider hosts the infrastructure components traditionally present in an on-premises data center, including servers, storage, and networking hardware, as well as the virtualization or hypervisor layer.
