Infrastructure as a Service (IaaS)
A cloud computing service model that provides scalable computing resources, servers, storage, and network capability as infrastructure. The three most common models of cloud computing services are IaaS, Platform as a Service (PaaS), and Software as a Service (SaaS). These models are built or stacked on top of each other, starting with IaaS at the bottom, PaaS in the middle, and SaaS at the top.
