With all the debate on public, private and hybrid clouds one of the main missing points is hard data: what is the actual, real economic impact of choosing a specific cloud model. We will present the results of an extensive survey of cost models, what is the impact of choosing an open source cloud platform like OpenNebula, the difference between planning for “cattle or cows” and how to compare different clouds using reliable performance metrics. We will also present a small sample of potentially relevant open source project that may help in deployment and management of ad-hoc cloud platforms.
