Abstract

Hybrid migration of enterprise system is to move some components to the cloud, and leave others on premise based on their security or performance requirements. To make hybrid migration strategy, one challenge is how to choose constraints and use them to help determine which components to migrate, and which cloud to use. Existing methods, however, either limit to calculate the quantifiable constraints to generate several alternatives or just list all constraints without stating how to analyze and use them to filter alternatives. In this paper, we extend existing method to a two-phase process: 1) use quantifiable constraints to generate several alternatives; 2) use AHP (Analytic Hierarchy Process) to automate the best solution selection process based on the hierarchical unquantifiable constraints. Analysis shows that our method takes advantage of the accuracy of the quantifiable parameters as well as analysts’ subjective judgment of the importance of the unquantifiable constraints, so that generates a more precise solution meeting enterprise’s subjective requirements.
