Web集群负载可扩展性架构分析及性能评价

Analysis and Performance Evaluation of Web Server Extensible Architecture Implementing Cluster and Load Balance

摘要:

本文通过对基于Apache的Tomcat集群和基于Nginx的Tomcat集群的配置，在相同网络环境下进行单位时间内处理请求数、平均响应时间等性能的测试，提出一种更具扩展性的Tomcat集群，既融合了Nginx高效节能特点，又具备Apache的灵活性和普适性优点。通过分析、设计和性能测试，验证了这种Web服务器集群在性能和实际操作中的优越性。

Abstract: Configuring Tomcat clusters based on Apache and Nginx respectively, and comparing the performance including TPS (Transaction Per Second) and ART (Average Response Time) under the same network environment, a more extensible structure combining the effectiveness and resource-saving of Nginx and the flexibility and popularity of Apache is designed. Finally the analysis, design and the performance test of the proposed web server cluster are demonstrated superior on performance and practical operation.
