OpenNebula is an open-source tool for managing virtual infrastructure in data centers. It provides a uniform management layer that can orchestrate multiple hypervisors and technologies. The presentation discussed OpenNebula's features from the perspectives of cloud providers and integrators, including how to build clouds, develop drivers, and interact programmatically. It also covered advanced deployments like clustering, hybrid clouds, and virtual data centers.
