Cloud computing promises on-demand scalability and flexibility for the enterprise environment and open source products have a large presence in this area. The authors have devised an elaborate set of criteria for evaluation and comparison of open source IaaS cloud computing solutions which can be used for ranking and choosing between the available products. They explain each criteria group, and give both the rationale and the estimated impact of the criteria. They also briefly introduce a number of most common open source cloud computing IaaS solutions to be evaluated using the explained criteria.
