Thomas and Flo really went and started a consulting company. We'll show how we use OpenNebula everywhere to achieve the best possible flexibility for sometimes totally conflicting use cases. A bit of architecture, a few bits about security vs. flexibility and definitely a few funny mistakes to learn from.
