摘　　要：提出一种利用公有云实现网站性能伸缩的技术方案,通过在公有云上建立一个反向代理服务器,将来自源网站的内容缓存到公有云上,进而可以利用公有云强大的计算和网络资源,实现在非常时期的海量访问量的应对。论述了方案背景,分析了方案原理和涉及的主要技术,并介绍实施过程和测试结果。提出的方案具有高效性,普适性,安全性和经济性的特点。由于所涉及的均为成熟技术,此方案可直接用于生产环境中。This paper proposes a technical solution to realize the website performance flexibility by building a reverse proxy server on public clouds. This solution caches the contents from the source website and takes advantage of the powerful computing and network resources of public cloud to deal with the massive data flow during the very period. This paper firstly describes the background, then analyses the principle of the solution and the main technologies involved, and finally describes the implementation process and evaluation result. The solution proposed in this paper is of high efficiency, universal applicability, good safety and economy. Since all the technologies involved in this solution are mature, it can be directly used in production environments.
