摘要
介绍了集群和负载均衡技术的概念,在省级数据集中实施过程中利用集群技术部署了主机、数据库和中间件系统,有效克服了单点故障。重点分析了中间件系统部署Web集群和App集群中软件代理服务器和硬件负载均衡服务器的区别,对省级集中系统的软件代理服务器性能提供了全面测试方案,得出的测试结论为:软件代理服务器能承载的合适在线数为一有限值,较大在线用户应使用硬件设备进行负载均衡,并对硬件负载均衡设备BIG IP F5的实施进行了详细描述。
The concepts of cluster and load balancing, deployed host computer, database and middle-are using cluster are introduced, the problem of single-point is solved, the difference of soft proxy server and hardware device of load balancing in website server and application server cluster are analyzed. A entire test scheme for soft proxy server is brought out and a conclusion is received, that is a soft proxy server＇s processing power is limited and hardware device of load balancing should be used in large numbers of users, BIG IP F5 is used in the provincial data integration system, the scheme of deploying is described in detail.
