Framework Development With High Concurrency And High Stability For A Medium-Sized E-Commerce Website Over The Cloud Platform

This thesis aims to develop a e-commerce framework for medium enterprises electric business platform,which has the characteristics of high concurrency,high stability and less cost.It can also improve the user experience.At present,many small and medium-sized retail enterprises,foreign trade companies have their own e-commerce platform.Along with the promotion for enterprise’s brand awareness,as well as the business expansion,the security of e-commerce platform and load capacity is subjected to the test.During the promotion and celebrate,the e-commerce platform will accept the large centralized access of users.This time,because of a shortage of the platform architecture,the e-commerce platform will appear a series of serious problems.The motivation of this thesis is to use the least cost,to build a high concurrency,high stability,easy extension e-commerce platform.At the same time,it can adapt to the changing business environment.The main work of this thesis is as follows:1.This thesis adopts the distributed cache and file database system to constructs the content distribution platform.A distributed "consistency" algorithm is proposed.These will improve the real-time performance.And users will visit the platform more quickly.2.This thesis adopts the technique of message queue and the business process software by our own.It can deal with the complex business processing.An improved business message processing mechanism is proposed.These can also improve the security and scalability of the e-commerce platform.3.To deal with concurrent high requests,we not only using the load balancing technology for the user visits,but also using the load balancing core idea.We proposed a load balancing algorithm by software for the cloud platform of business processing,and built the load balancing system for the business process and data access.The new e-commerce sites structure has the following advantages: First of all,the new system can support a large number of users to visit at the same time.The second,we can improve the bearing capacity of the system by add servers.In the end,we make it more flexible,stable and security.So much technology has been used in the system.Such as the load balancing technology,the message queue technology and the software of business process.These give the e-commerce a strong support.
