基于云计算的海量数据存储模型

Massive Data Storage Model based on Cloud Computing

针对目前网络产生的数据越来越多以及随之而来的海量数据的存储问题,在云计算技术上,依据Hadoop及虚拟化技术,提出了基于云计算的海量数据存储模型。将医院信息化的海量数据部署在Hadoop平台上,根据云计算的核心算法MapReduce来处理数据,最后将数据存储在虚拟资源池中。通过实际的应用,该模型可以很好地克服现行的存储方式存在的不足,解决海量数据在存储当中存在的问题,并且能够很好地提高存储的效率。

For the problem of massive data storage on the network,and based on the hadoop and virtual technologies,the massive data storage model based on could computing is proposed.The massive data of hospital informatization is applied on the hadoop platform and processed by MapReduce,the key algorithm of cloud computing,and finally the data is stored in the virtual pool.Practical application indicates that the model could conquer the shortage of present storage mode,solve the problem of massive data storage,and effectively raise the storage efficiency.
