Infrastructure-as-a-service (IaaS) is a form of cloud computing that provides virtualized computing resources over the internet. IaaS is one of the 3 main categories of cloud computing, 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.
