志愿云计算研究综述

摘要

With human society stepping into big data and cloud computing era,volunteer cloud computing (VCC)is a new direction for cloud computing,which will provide great potential applica-tion in scientific research.In order to help reader understand the theoretical and piratical connotation of VCC,this paper described the difference and relation among VCC,volunteer computing and cloud computing,identified the opportunities of VCC in lowering the entry barrier of cloud computing,pro-moting the development of domestic software and hardware and energy saving and emission reduction. Then the paper analyzed the operational mechanism of typical VCC project like Cloud@Home,Nebu-las,CernVM,BoincVM.In the end,the paper pointed out that the enlightenment of the VCC lied in policies and regulations,key technology and criterion and engineering application.%人类社会进入大数据和云计算时代，志愿云计算作为云计算的一个新的发展方向，在科学研究中具有较大的应用潜力。为深刻理解志愿云计算的理论内涵和应用现状，通过综述国内外相关研究文献，阐明了志愿云计算和志愿计算、云计算的区别和联系，明确了志愿云计算在降低云计算准入门槛、促进国产软硬件技术发展和节能减排等方面存在的机遇，对典型的志愿云计算项目 Cloud@ Home、Nebulas、CernVM 和 BoincVM 运行机制进行了深入剖析，最后给出了志愿云计算在政策法规、关键技术和标准以及工程应用等方面的启示。
