This research study stresses upon the comparative analysis between commercial and non-commercial Enterprise Service Buses (ESB) for large-scale organizations. We have used Multi Criteria Decision Analysis (MCDA) method known as Analytical Hierarchy Process (AHP) based on three criteria that is Information Security (IS), Interoperability and High Availability (IHA). Many comparative analysis reports and papers are available having proven results of comparing non-commercial ESB(s), however, very few reports were found having performed their analysis on commercial ESB(s). We have performed this analysis on the basis of mathematical and graphical proofs by comparing commercially known ESB that is Oracle ESB with two non-commercial yet very famous ESB(s) that is Mule and Fuse. This research analysis will motivate decision makers to choose the best rated ESB on the basis of our criteria. To achieve our objective, we have presented the problem as hierarchy, established the priorities, criteria, and performed mathematical computing and presented graphs to prove our analysis.
Key words: Software engineering, service oriented architectures, enterprise service bus,multi criteria decision analysis, analytical hierarchy process, information security.
