Learn how other people are using OpenNebula today to deploy clouds in a snap, all the way from micro clouds to massively big, federated clouds. Learn performance and tuning tips shared by other OpenNebula fellow users to leverage other open-source projects like Ceph, LizardsFS, Open vSwitch and Puppet into making your cloud resilient, fast, flexible and massive.

We will also shed some light on other OpenNebula compoments that have grown indispensable to their users, like hooks, AppMarket to share images accross OpenNebula deployments, OneFlow to manage services and OneGate to report metrics directly to OpenNebula.

The present status of Cloud and Virtualised Machine instances is very chaotic; different Vendors doing their own thing, every hypervisor needing its own magic and various cloud instances imposing their own site requirements. The RainDrops project aims to reduce the impact this has on users, giving them a unified interface ( web, git and REST ) that they can define their requirements against. And let the system handle the various requirements.

In this presentation we aim to define the scope of the problem and demonstrate our solution. Our demo will consist of defining a single kickstart file, and then using that to build multiple instances for different vendors and technologies, with very little effort and no vendor specific configs needed.

The raindrops project has been in development and closed testing upto this point, we hope to use the Fosdem talk to launch it publicly.

In this talk we will discuss how the build system and QA of CentOS is implemented using a private cloud: OpenNebula. We will focus on the challenges of integration, advantages and workflow. We will also demonstrate how to implement and automate a building system and QA tasks by creating a private cloud on the fly with a CentOS laptop using OpenNebula. Administrators will benefit from this technique -and its simplicity and ease of deployment- to overcome the complexity of this kind of systems.

OpenNebula is a lightweight, robust, and at the same time highly modular solution for data center virtualization. This talk will describe the OpenNebula architecture, and how it can be extended to interact with new technologies, or tailored to meet your individual datacenter requirements.
