This document discusses hyper-converged infrastructure (HCI) and virtualization. It begins with an overview of traditional IT infrastructure, including separate server, storage, and network components. It then explains how virtualization abstracts resources and allows multiple operating systems to run on a single physical server. Finally, it introduces HCI, which integrates compute, storage, networking and virtualization into a single scale-out system that is software-defined.
