Abstract

Popular websites such as Google and Facebook must have an extremely large clients and providing such clients only with a single web server is absolutely insufficient. To support service availability, two or more servers are required. This, however, needs a load balancing system. A load balancing server receives web traffic and distributes the requests to such multiple servers. Load balancing can be implemented with special hardware, software or a combination of both. The purpose of this research is to develop a load balancing system with HAProxy as a software-based load balancer and Heartbeat as failover software and provides comparisons of the performance of several balancing algorithms on it. The results show that without a load balancer, the load cannot equally be distributed. The system average failover time when an active server down is 10ms. The Leastconn algorithm, in general, outperformed the Round-Robin and Source algorithms in terms of connection rate, response time, throughput, and failed connection.

web服务器负载均衡算法在HAProxy和Heartbeat上的性能比较

像Google和Facebook这样的热门网站必须有一个非常大的客户端，而仅仅为这样的客户端提供一个web服务器是绝对不够的。为了支持服务可用性，需要两台或更多的服务器。然而，这需要一个负载平衡系统。负载均衡服务器接收web流量，并将请求分发给多个服务器。负载平衡可以通过特殊的硬件、软件或两者的组合来实现。本研究的目的是开发一个负载均衡系统，其中HAProxy作为基于软件的负载均衡器，Heartbeat作为故障转移软件，并提供几种平衡算法在其上的性能比较。结果表明，如果没有负载均衡器，负载就不能均匀分配。当活动服务器关闭时，系统的平均故障转移时间为10ms。一般来说，在连接速率、响应时间、吞吐量和失败连接方面，Leastconn算法优于Round-Robin和Source算法。
