There is a rapid increase in the size of Data Centers (DCs) used to provide cloud computing services. It is commonly agreed that not all properties in the middleware that manages DCs will scale linearly with the number of components. Further, \"Normal failure\" complicates the assessment of the performance of a DC. However, unlike in other engineering domains, there are no well established tools that allow the prediction of the performance and behavior of future generations of DCs.
