【摘要】：本选题主要是为了研究出一套适应于中大型企业电商网站架构,在保证高并发,高稳定的同时,降低企业成本,提高用户体验。目前,很多中小型零售企业,外贸企业都有了自己的电子商务平台。随着企业品牌知名度的提升,以及业务的扩大,电子商务平台的安全性,承载能力也经受着严峻的考验。尤其在假日促销,店庆活动时,电商平台将接受更为庞大的用户集中访问。这个时候,由于平台架构的一些不足,会导致一系列严重的问题。本文的动机就是使用最少成本,有效地利用现有硬件资源的前提下,架构出高并发,高稳定,易扩展,同时适应不断变化的业务环境的电商网站架构。本文的主要工作成果如下:1.采用分布式缓存,文件数据库系统,构建了内容分发云平台,提出了改进的分布式“一致性”算法,将内容实时,快速,准确的呈现给用户,提高了用户体验;2.采用了消息队列技术以及自主研发的业务处理与调优软件,来实现复杂业务的处理,提出改进的业务消息处理机制,提高了业务处理的安全性和扩展性;3.为应对高并发请求,从用户接入、业务处理、数据访问等方面使用了负载均衡技术,提出了针对业务处理云平台的软件负载均衡算法,构建了拥有自身特色的负载均衡系统;新的电商网站架构具有以下优势:新系统可同时支持大量用户并发访问;新系统具有可扩展性;在业务处理上,新系统具有灵活性大、稳定性高、安全性强的特点;新系统所采用的分布式,负载均衡、消息队列技术,给整个电商架构提供了强有力的支撑。
[Abstract]:The main purpose of this paper is to develop a set of ecommerce website architecture suitable for medium and large enterprises, which can reduce the cost of enterprises and improve user experience while ensuring high concurrency and high stability. At present, many small and medium-sized retail enterprises, foreign trade enterprises have their own e-commerce platform. With the promotion of enterprise brand awareness and the expansion of business, the security and carrying capacity of e-commerce platform also stand a severe test. Especially in holiday promotion, shop celebration activities, e-commerce platform will be more extensive access to users. At this time, due to some platform architecture deficiencies, will lead to a series of serious problems. The motivation of this paper is to use the minimum cost and utilize the existing hardware resources effectively to construct the ecommerce website architecture which is high concurrency, high stability, easy to expand and adapt to the changing business environment at the same time. The main achievements of this paper are as follows: 1. By using distributed cache and file database system, a content distribution cloud platform is constructed, and an improved distributed "consistency" algorithm is proposed, which presents the content to users in real time, fast and accurate, and improves the user experience. 2. Message queue technology and self-developed service processing and tuning software are used to realize complex business processing. An improved service message processing mechanism is proposed to improve the security and scalability of service processing. 3. In order to deal with high concurrency request, load balancing technology is used in user access, service processing, data access and so on. A software load balancing algorithm for service processing cloud platform is proposed, and a load balancing system with its own characteristics is constructed. The new ecommerce website architecture has the following advantages: the new system can support a large number of users concurrent access at the same time, the new system is extensible, the new system has the characteristics of great flexibility, high stability and strong security in business processing. The distributed, load balancing and message queuing technologies used in the new system provide a strong support for the whole ecommerce architecture.
