This document provides an introduction to cloud computing with OpenNebula. It discusses infrastructure as a service (IaaS) and the different types of cloud deployments including public, private and hybrid clouds. It then describes the challenges of managing an IaaS cloud, and how OpenNebula provides a uniform management layer to address these challenges. The document outlines the key aspects of the OpenNebula model and architecture, including its open source nature, enterprise features, and ability to manage different infrastructure technologies. It concludes with a basic overview of an OpenNebula deployment.
