Research On The Dynamic Management Mode And Technology Of Components Supporting The Scalable SaaS Application

With the rapid development of internet technology and economy, thetraditional software delivery model has changed, the SaaS software service deliverymodel appears. Face to the rapid growth of demand, many companies want toquickly get involved in this market, so we propose an innovative service modelnamed Biris (Bilateral Resource Integration Service, Biris), introduce a fourth cloudcomputing platform named Biris-Cloud. The platform uses resources integration,component dynamic manage technology to create cloud service center (iSC) andestablished a SaaS business application system to provide service to customer. Thepaper’s core work is dynamic management mode and operating technology of SaaScomponent which deployed and run in the cloud environment.The thesis analysis current SaaS application at home and abroad, andsummarizes the critical theory, core technology and characteristics of SaaS model,makes a demand analysis to the component manage system. At the beginning, thepapers introudce the Biris-Cloud and some key concepts, the gives the applicationscene of this problem. After that, the paper analyses the function of the componentsystem from different roles in the system and puts forward the main content of theresearch, and resolve the storage problem of the large number components.For the characteristics of SaaS component on the Biris-Cloud platform, thepaper analyses the related theory and key technology, establishs a componentdescription model based on ontology which provide information support to thecomponent mangement technology. With an depth analysis on the realization ofHDFS(Hadoop Distributed File System), we propose a dynamic storagemanagement of SaaS component. Then the paper gives a formal description of thecomponent deployment and proposes an algorithm to resolve this problem. We alsodesigned and implement the component run-state monitoring functions for theBiris-Cloud component manage system.To verify the content of the research about the component management, wemake an overall system design to the system, such as structural design, functiondecomposition and give an overall system running process and database design.With the analysis and research on the content of related theory and the technology,we develop the component manage system and conducted a validation to the relatedbusiness process, which indicates the system effectively supports the scalablefeature of SaaS application.
