Research On Key Techniques Of The Automatic Construction Of Internet Service Center

Biris-Cloud is a SaaS-based forth-party platform which provides on-demandservices. Any organization in real world could establish an Internet Service Center(iSC) on the platform and use the integrated virtual resources to serve customers.Having Biris-Cloud platform as the background, this paper studies about coretechnologies in the construction of an Internet Service Center. As the constructionof iSC is very complicated for involving many aspects, the correctness and integrityof the definition is hard to guarantee. To solve this problem and standardize thebasic elements that builds up an iSC, a model of iSC is needed. Also an applicationframework based on the model is also a must.The structure and design of multitenancy-based business components couldheavily influence the functions and structure of the whole framework. So this paperfirstly analyses the structure and developing process of multitenancy-basedcomponents. By taking practical components as examples, we introduces themultitenancy design of the framework, which is also the main idea of this paper.This paper then proposes the metamodel of iSC by analyzing the basicelements of an iSC, and use it to constain the definition of iSC. To make themetamodel practical and verify its correctness and effectiveness, this essay proposesthe iSC automatic construction framework, which is based on the metamodel of iSCand works in every period of the lifecycle of an iSC like definition creationperiod, definition parsing period and running period. The framework is a strongsupport of the definition and running of iSC.First of all, this essay provides the iSC definition creation tool set, aiming tosupport the definition of iSC obeying the metamodel. The tool set covers mostelements that forms the iSC. In the parsing period, a parsing engine is provided toparse the definition of iSC.To support iSC to run in the cloud environment of the platform and make useof the most important features of cloud computing like virtualization, distribution,Saas and multitenancy, the framework provides a branch of modules including messaging module, multitenancy business component runtime framework, businessprocess engine, data service and many more.We also created some working cases. We design and implement an iSC whichhas the basic business functions in order to prove the theories, technologies anddesigns in this paper.
