Modeling And Analysis Of Service Oriented Cloud Application Architecture

With the increasing of the number and complexity of enterprise applications,enterprise informatization construction is facing more and more challenges. ServiceOriented Architecture and Cloud Computing due to their respective advantages aregradually adopted by enterprises. Integration of Cloud Computing and Service OrientedArchitecture is becoming new research focus in the field of enterprise informatizationconstruction. Based on DoDAF, a service oriented cloud application architecture modelingmethod is proposed. Then the fitness and coupling of cloud application are investigated.Specific research contents are as follows.As there are few mature modeling methods for SOA and Cloud Computing, theDoDAF is adopted after exploring the relationships among DoDAF, SOA and CloudComputing. An architecture modeling method based on requirement analysis, functionaldomain decomposition, business process analysis, service description and cloud resourcesanalysis is then proposed. Besides, the process of transforming static architecture toexecutable architecture is illustrated.Intranet portal is the integration platform for enterprise information application. Thearchitecture of Intranet portal is constructed, followed by the structured analysis processbased on Petri Net.With the lacking of systematic and principled method of Cloud applicationdeployment, an analysis method based on economic fitness, the availability fitness andfunctional fitness is raised.Coupling is one of the important quality attributes of the architecture. In the end ofthe thesis, in the points of the mapping between service and capability, service decriptionfor itself and service interaction, a coupling analysis method is presented based onfunctional coupling, interface coupling and interaction coupling. In addition, the N squarediagram is adopted for coupling characteristics analysis.
