E-commerce System Design And Implementation Base On Silverlight And Virtualization Cluster

The beginning of this century,The rapid development of the Internet industry generates alot of industries had never heard of，the Internet gradually change people’s way of life but alsopromoted the development of the whole society. It was in this period, e-commerce companywas born. Relying on the Internet for e-commerce with efficient online trading activity thatrequires third-party payment instruments and powerful logistics system in this one as aguarantee, providing reliable service, and now even the insurance company for thee-commerce merchants carried into the return protection. Buyers and sellers throughout thepurchase process to achieve the transaction on the Internet to reach,Buyers and sellers do notneed to meet, and to understand the commodity through real-time voice chat tools one-commerce sites, which not only saves time, but also saves the cost, greatly improvingefficiency.In terms of project development is to select the type currently used to select the mostB2C model,the development of system based on MVC architecture, calls between levels oneby one, the architecture has the characteristics of high cohesion and low coupling.E-commerce systems development process is completely oriented commercial reale-commerce system, fight side can truly improve the comprehensive ability to maintain thesystem from the marketing side and running. Internet companies use technology and businessphilosophy replacement very fast, so for business managers who need to seize the currentturnover, market share, but not only these, but also through the analysis of marketing dataplanning the future direction of development, allowing companies not strive in the futuremarket competition.Achieve innovation of B2C online sales system on the use of Silverlight technology andvirtualization cluster technology to achieve innovation. Use Silverlight front-end interface tosolve the problem, the use of virtualization to protect the server cluster running smoothly.Overall system based on B/S architecture development, Silverlight, Ajax and JavaScripttechnology development system with the use of front-end interface, making the page morebrilliant solve the awkward problem of the traditional controls, while also providing a richclient technology. Background code developed using C#language, database usingSQLServer2008, here we access to the database through a WCF service, execute LINQ toSQL language instead of traditional SQL statements. In the end run using similar commercialvirtualization cluster using VMware’s virtualization products related companies to create and manage virtual machines, constructed by a certain scale cluster composed of virtual machines,virtual machines associated future operations are vSphere5.1customers client software runson, operation and maintenance efficiency has been secured.The system of B2C online sales on architecture is divided into front-end interface layer,presentation layer, business logic layer, control management, load balancing layer, databaselayer cluster layers. Among them, the load balancing layer is actually not an absolute level,but embedded in the control of the management of the load balancing algorithm, where thepurpose of adding load balancing layer to simulate the same commercial. The load balancingalgorithm used,the development of the system mainly based on IP through Hash algorithm, toachieve equal distribution of requests from the interface to each server. In this case, add anddelete virtual machines, and even affect the server downtime and replacement of the entiresystem can be reduced to a minimum to ensure smooth operation of the system in any case.After the end of the system development continues to be implemented on a cluster ofvirtualization deployments and related performance tests to identify system bottlenecks,defined the future direction of research to address these issues.
