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 examples and confirms that the Hadoop as a distributed cloud computing platform is more likely to develop and process large data in parallel. Finally, prospects the implementation of high availability and efficiency of Hadoop.
