弹性Web Cache集群设计与实现

DESIGN AND IMPLEMENTATION OF ELASTIC WEB CACHE CLUSTER

为在Web cache系统中实现弹性资源供给,提出了同时使用本地资源和云计算资源的弹性Web cache集群。阐述弹性Web cache集群的设计目标、功能模块、数据处理流程;实现基于Linux内核程序的弹性Web cache集群软件平台;对弹性Web cache集群进行性能测试。实验证明,弹性Web cache集群能够实现高效的负载均衡,有效处理Web突发请求和热点对象问题,显著改善系统可靠性和可用性。

To achieve elastic resource supply in Web cache system, we propose to simultaneously use elastic Web cache cluster of both the local resource and cloud computing resource. In the paper we describe the design target, function modules and data processing flow of the elastic Web cache cluster, implement an elastic Web cache cluster software platform which is based on Linux kernel program, and carry out the performance test on the elastic Web cache cluster. Experimental results show, the elastic Web cache cluster can achieve efficient load balance, handle the problems of Web burst requests and focusing objects effectively, and improve the reliability and availability of the system significantly.
