What Bugs Live in the Cloud?: A Study of Issues in Scalable Distributed Systems.

We performed a detailed study of development and deployment issues of six open-source scalable distributed systems (scale-out systems) by analyzing 3655 vital issues reported within a three-year span. The results of our study should be useful to system developers and operators, systems researchers, and tool builders in advancing the reliability of future scale-out systems. The database of our Cloud Bug Study (CbsDB) is publicly available.
