高并发性Web应用平台研究与实现

随着信息化的发展,web应用平台被越来越多企事业单位使用,用户人数越来越多,并发访问量越来越大。为此,web应用平台的高并发问题也成为了人们关心的热点问题。为了解决web平台的高并发难题,设计并实现了一种高并发性Web应用平台。平台采用应用负载均衡和数据库集群技术分解web和数据库访问的压力,通过划分安全域保证平台安全,利用数字签名和存储过程技术保证数据完整性;提出了一种基于字典数据和统计结果缓存的数据库访问方法,降低数据库访问频率;平台已于2014、2015年在吉林省高考网上报名中应用,实践证明平台可以支持大量用户的高并发访问。

The Research and Realization of the Web Application Platform with High Concurrency

With the development of information, the web application platform has been used by lots of enterprises and institutions. Along with the increase in user number, the concurrent access also increased. Therefore, the problem of high concurrent in web application platform has become a hot issue which people cared. To solve the problem, a kind of high concurrency web application platform has been designed and implemented. The platform adopts the technology of database load balancing and database cluster to release the pressure of web and database server. At the same time, by dividing different safe region to ensure the security,utilizing digital signature and stored procedure to ensure the data integrity. This paper proposes a method of visiting database based on dictionary data and statistical results cache to re-duce the visit of database. The platform has been applied to On-line Registering System for NMT of Jilin Province. The practices shows that this platform can support mass concurrent access to a large number of users.
