基于Google的云计算技术

介绍了云计算技术.云计算技术可实现并行计算、分布式计算和网格计算等.以Google云计算平台为例,阐述了云计算三大关键技术:GFS分布式文件、BigTable分布式数据库以及Map-Reduce编程模型.基于Apache的Hadoop-0.20.2平台,通过WordCount实例,分析了云计算的实现机制与工作过程,并讨论了云计算技术的发展问题.

Cloud Computing Technology Based on Google

This paper introduces the basic concept of cloud computing.Cloud computing can realize parallel com-puting ,distributed computing grand and grid computing. This paper introduces three key technologies of clouding computing based on the cloud computing platform of Google:Google File System , Distributed database-BigTable and Map/Reduce.Besides ,based on Hadoop-0.20.2 platform of Apache ,this paper analyzed the realization system of cloud computing and working process through WordCount and also analyzed the challenge of cloud computing.
