Xiaowei Wang successfully defended PhD thesis

On January, 11th 2017, our group member Xiaowei Wang successfully defended his PhD thesis. In the last years, Xiaowei worked on a new concept for reliability assessment and engineering of cloud systems. In contrast to related work, his concept is able to measure individual cloud component reliabilities and, based on this, to derive an assessment for the whole cloud system. His work showed, that his estimations are as good as measuring the reliability of the whole system at once. But his approach may also support predictions of the reliability of a cloud system after changes, which is left for future work.
