面向Hadoop的云计算核心技术分析

The Core Technology of Hadoop-Oriented Cloud Computing

在企业以海量数据处理能力为核心竞争力之一的时代,云计算技术的出现为此提供了良好的解决方案。首先,研究分析了云计算技术的开源实现Hadoop的核心内容:分布式系统文件HDFS和MapReduce算法模型;然后,通过实例阐述了面向Hadoop的分布式云计算平台的构建,证实了Hadoop是一个更容易开发和并行处理大规模数据的分布式云计算平台;最后,对如何实现Hadoop的高可用性和高效性进行了展望。

In the era of using mass data processing capacity as one of the core competitiveness, the emergence of cloud computing technology provides a good solution for the enterprise. Firstly, analyzes the core content of the Hadoop as the open source realization of cloud computing technology： Hadoop distributed file system （HDFS） and algorithm model MapReduce. Then, elaborates the construction of Hadoop-oriented distributed cloud computing platform through ex- amples and confirms that the Hadoop as a distributed cloud computing platform is more likely to develop and process large data in parallel.
