Size Estimation of Cloud Migration Projects With Cloud Migration Point (CMP)

One of the major obstacles to enterprise adoption of cloud technologies has been the lack of visibility into migration effort and cost. In this paper, the authors present a methodology, called Cloud Migration Point (CMP), for estimating the size of cloud migration projects, by recasting a well-known software size estimation model called Function Point (FP) into the context of cloud migration. They empirically evaluate their CMP model by performing a cross-validation on six different small-scale cloud migration projects and show that their size estimation model can be used as a reliable predictor for effort estimation. Furthermore, they prove that their CMP model satisfies the fundamental properties of a software size measure.
