Abstract:

Enterprise IT system architecture is changing as the rapid development of cloud computing technology, an enterprise cloud migration suitability evaluation method based on Service Oriented Architecture (SOA) modeling and simulation is proposed to promote the decision-making level of whether the enterprise IT system is suitable for deployment in private cloud or not. Through enterprise cloud application system architecture view modeling and executable Colored Petri Nets (CPN) model simulation, the method establishes cloud migration suitability evaluation metrics from enterprise cloud application demand and cloud service attribute. Combination of both qualitative analysis and quantitative methods is used in the comprehensive evaluation process and analysis steps of the enterprise cloud migration suitability Analytic Network Process (ANP). Finally, the feasibility and effectiveness of the method is validated by an enterprise use case.
