随着传统互联网的进一步发展，人们对网络资源的使用需求发生了变化，快速构建稳定、易扩容的服务越来越 成为服务关键。服务需求变更快，从产生、成熟到被遗忘周期更短，如何在固定且有限的资源上提供服务越来越成为研究热 点。本文在现有技术的基础上，基于Hadoop 平台，实现智能冗余服务，满足以上需求。

With the further development of the traditional Internet, the demand for the use of network resources has changed, and the construction of scalable and dilatant service is more and more important. Service requirements change quickly. The cycle from generation to maturity then to be forgotten is shorter. How to provide services on fixed and limited resources are increasingly becoming a research hotspot. In this paper, based on the existing technology, an intelligent redundancy service based on the Hadoop platform is implemented to meet the above needs.
