摘要
先介绍了云计算产生的背景、概念、基本原理和体系结构，然后以Google系统为例详细阐述了云计算的实现机制。云计算是并行计算、分布式计算和网格计算等计算机科学概念的商业实现。Google拥有自己云计算平台，提供了云计算的实现机制和基础构架模式。该文阐述了Google云计算平台：GFS分布式文件、分布式数据库BigTable及Map／Reduce编程模式。最后分析了云计算发展所面临的挑战。
This paper introduces the backgrounds, concept, basic principle and infrastructure of cloud computing firsdy.Then it surveys implementation mechanism of clouding computing based on the instances of Google.Cloud computing is the system in enterprises based on the concepts of computer science. These concepts include parallel computing, distributed computing and grid computing. Google has his own platform of cloud computing. It provides implementation mechanism and infrastructure of cloud computing. This paper surveys the platform of cloud compudng：Google File System, Distributed database-BigTable and Map/Reduce. Finally the paper analyse the challenge of cloud computing.
