The study on magnanimous data-storage system based on cloud computing

Dongping Cheng

Cloud computing is a computing and a brand new business model, large amounts of data storage issues related to cloud computing emerged in this model. In order to better solve the storage problem of cloud computing, this paper studies on the cloud computing and storage system, focusing on analysis of the distributed computing framework of Apache open-source organization, called Hadoop. First, it focuses on the study of the storage infrastructure of HDFS file system which lays the foundation of the effective design of Hadoop; then it analyzes the programming model of Map Reduce and HBase, in order to exploring the methods of system designing; in the end, based on large amounts of models of data stored design rooted to could computing, it testing the system, and compares the system in this paper to traditional designed system in the area of CUP load and memory usage, and finds out if the effect on CPU caused by the system in this paper is in an acceptable range, this system will has a very excellent memory usage advantages in Name Node.
