摘　　要：随着信息时代的到来、互联网技术的高速发展,随之而来的不可避免的一个至关重要的问题就是web系统性能的好坏。当多个用户同时访问同一个资源,当同一时刻服务器接收到数以亿计甚至更多的请求,引起的网路堵塞或者是服务超载会出现请求失败、系统响应缓慢,甚至会导致web网站的崩溃,这种高并发性问题引起的后果是难以想象的。本文针对web系统的高并发业务处理方式之负载均衡方式进行相对深入的研究,将对三种实现负载均衡的方式进行详解。可根据情况合情合理地选择合适的负载均衡方式,以提高系统对高并发业务处理的响应速度,提高系统的整体性能。本文对大型web系统的性能提高有一定的帮助作用。With coming of the technology age and the rapid development of Internet technology, an unavoidable and crucial problem is the performance of web system. When multiple users access the same resource at the same time, when the server receives tens of thousands or more requests at the same time, the network congestion or service overload will result in request failure, slow system response, and even the collapse of the web site. The consequences of this high concurrency problem are unimaginable. In this paper, the load balancing of high concurrent service processing mode in web system is studied in depth, and three implementation methods of load balancing are introduced in detail. The appropriate load balancing mode can be reasonably selected according to the situation to improve the response speed of the system to high concurrent business processing and the overall performance of the system. This paper is helpful to improve the performance of large-scale web systems.
