Research Of Enterprise Cloud Service Architecture Modeling Framework And Application

Cloud Computing is becoming the hottest technology of IT architecture due to theadvantages such as: Elastic, Rapid deployment, on-demand features to provide reliableservices; Service-Oriented Architecture, with the feature loose coupling, can make almost allof the resources of enterprise provided as services, increase reuse of resouces and higher theagility and capability of quickly response to change. The combine of them brings out the bestin each other, is the trend currently. However, none of these enterprise architectureframeworks can support modeling and analysis of the combinative architecture well.Synthesize the advantages of these mainstream enterprise architecture frameworks, proposeda modeling framework named Enterprise Cloud Service Architecture Framework (ECSAMF),which can support the modeling of cloud computing and SOA well.Based on Defense of Department Architecture Framework(DoDAF)2.0, UtilizedUPDM, TOGAF and CCMN to extend DM2, then acquired the Meta-Datas of ECSAMF,added the elements of SOA and Cloud Computing, at the same time, ensured the dataconsistency. Found the Meta-Models of DoDAF’s view models, and formalized, proposed adecide approach of recationships between each two models, analysited relationships of allDoDAF models, then provided a roadmap of modeling DoDAF models. At last, leaded intothe principle of DoDAF’s “Fit-for-Purpose”, make sure that ECSAMF not only support thewhole life of enterprise architecture in the environment of cloud computing or SOA, but alsoany part of it.In order to validate the availability and effectiveness of ECSAMF, selec ted the firsttrouble when implement the mixture of SOA and Cloud Computing, and where to implementapplications in cloud computing, proposed a Filtering Model based ECSAMF. First,customized a “Fit-for-purpose” describe framework from ECSAMF, utilized economical,serviceability and founctionality filter measures to analyze the conformity of the applicationsto cloud computing. The approach changed the subjectivity decision with historical data andindustry experience.Park A leaded cloud computing into the former enterprise architecture basedService-Orinted Architecture, utilized the Filtering Model to analyze the location of Visitor Management System, acquired its conformity to cloud computing, proved theexploitativeness of the Filtering Model which support applications designd Service-Oriented,and the practicability of ECSAMF.
