Cloud Computing has become an important paradigm for providing IT services. An important aspect that data centers which offer cloud services need to deal with is the reduction of their energy consumption. A suitable way for reducing the energy consumption and thus the energy costs is using energy efficient load distribution algorithms. These are commonly evaluated by simulation. Up to now, there are only few simulation tools for clouds that are freely disposable and those that do exist have hardly been compared in terms of their applicability for determining the energy consumption of clouds. Therefore, this contribution presents an analysis of simulators that investigates their suitability for determining the energy consumption of cloud data centers. The findings of the analysis will be supported by a unified experiment. The results demonstrate that existing work has limitations, for example in terms of components that are not considered to be energy- consuming.
