随着并行计算、分布式计算、网格计算的发展，出现了一种新的计算模式--云计算。它旨在在大规模网格的用户之间透明地共享数据，计算和服务。由于其具有“降低成本”、“增加业务灵活性”和/或“提供业务连续性”等优点，成为热点问题。介绍了什么是云计算，并以Google的云计算技术为例，总结了云计算中使用的关键技术，如数据存储技术（Google File System）、数据管理技术（BigTable）以及编程模型和任务调度模型（Map-Reduce），并对一些云计算厂商的实例进行了说明和比较。
With the development of parallel computing, distributed computing, grid computing, a new computing model appeared, called cloud computing. It aims to share data, calculations, and services transparently among users of a massive grid. It became a hot issue for its advantages such as “reduce costs”, “increase business flexibility” and/or “provide business continuity”. In this paper, we described what is cloud computing and took Google's cloud computing techniques as an example, summed up key techniques, such as data storage technology (Google File System), data management technology (BigTable), as well as programming model and task scheduling model (Map-Reduce), used in cloud computing, and then some example of cloud computing vendors were illustrated and compared.
