9:15-9:30: An Introduction to OpenNebula
|Ignacio M. Llorente, Project Director at OpenNebula|
We’re moving into a world of open cloud — where each organization can find the right cloud for its unique needs. A single cloud management platform can not be all things to all people, there will be a cloud space with several offerings focused on different environments and/or industries. The OpenNebula commitment to the open cloud flows directly out of its mission — to become the simplest cloud enabling platform — and its purpose — to bring simplicity to the private and hybrid enterprise cloud. OpenNebula exists to help companies build simple, cost‐effective, reliable, open enterprise clouds on existing IT infrastructure. The OpenNebula project is really vendor‐agnostic and completely driven by users needs with features that meet real demands. The session will introduce the OpenNebula project from different perspectives, ranging from its historical milestones and main contributors to its most relevant users and the size of their cloud deployments.

14:15 – 14:30: Clash of titans in SDN: OpenDaylight vs ONOS
|Elisa Rojas,, Research Director at Telcaria|
After the definition of the OpenFlow protocol and the birth of the SDN paradigm, different communities are fighting to develop the ONE reference SDN controller. During the last years, two specific projects: OpenDaylight and ONOS, supported by both the scientific community and industrial partners, compete to achieve that status. In this talk, we will present the features provided by each project and how they differ, as well as a perspective of their applications in the future.
