Design And Realization Of The Website Group Based On HTML5and Cloud Computing

The portals of government, enterprises and institutions often present universalway that from the center to local radiation. With the popularity of conduction,departments and units of the websites linked together to form a community website.They are unified in form, but they are actually isolated from each other in informationand can`t be coordinately managed. Site Management Cluster is the trend anddirection of portal development. The instructor`s research project "Technologytransfer Training Base of Beijing", is to make the service of technology transfersite-like in form, diversiform in method, industrialized in service and global incompetition. Its information service platform is the indispensable tools and methodsin reorganization of resources, business development and expanding its influence.Applications of B/S model solve the drawbacks that the applications oftraditional C/S mode bring:difficulties in deployment, update and maintenance. Butthe same time, it brings more dependence on the bandwidth of network and can`t copewith the drawback that the network connection is unstable. When integrate the systemin heterogeneous environments, the data distributed in RDBMS of different businesssystem are extraordinary difficult to interact with eachother. Even when usingthird-party tools to achieve distributed data redundancy problems are difficult to solve.Cloud storage enviroment is more suitable across dispersed multiple data center. Theresearch on how to apply distributed storage system is a suitable way to solve theproblem before. The content search function is indispensable in current informationmanagement applications,and therefore researchs on distributed search framework areneeded under distributed storage environment. In addition to this outside,system loginacross sites of cluster,information interaction between sites and applicationsystems,logging system also have necessary in improving the functions.Introduces the principles and advantages of HTML5Offline Web technology,application of the principle of distributed cloud storage architecture, features ofSpring MVC framework, principle of Log4j logging system, WebService frameworkof Apache CXF, ActiveMQ message bus technology, FreeMarker template technology,CAS technology and research on application of Elasticsearch distributed retrievaltechnology. Then start from the needs of website group, set out the functional andnon-functional requirements, and then design the business system,datamodels,communication API and the main classes of the cluster. Finally, achieve thecore function of the system.The main research point is the roadmap of website group system constructionthat based on HTML5and cloud storage technology to have the website grouphigh-performance and excellent user experience, and present a viable solution toimprove the most current website clouds based on traditional database and technology.
