Design And Implementation Of Network Disk Based On Cloud Storage

With the rapid development of network technology, the world has entered the era of big data. In the era of big data, the storage of massive data becomes an urgent problem to be solved. Large capacity data storage and high-speed upload and download have become the most scarce demand. Cloud storage system is a very effective solution for mass data storage. Cloud storage is the application of clustering technology, virtualization technology, grid technology or distributed file system technology, etc., which consists of a large number of different types of storage devices through the applications of software integration, to provide data storage and business access functions of the system. Cloud storage combines a large number of storage devices of the network to work together to provide services for data storage and business access. This dissertation studies the system structure of data distributed cloud storage system and related technology based on the design, and the implementation of the enterprise network disk system based on cloud storage.Firstly, this thesis makes a deep research on cloud storage system platform and open source distributed file system, and studies the structure and key technology of cloud storage system.Then it designs the general framework of enterprise network disk system, cloud storage technology and the structure of network storage system based. It also fully designs the main business of processing data flow network disk system, the overall function of the system structure, system component model and the database model.Finally, using Spring MVC and Mongo DB technology, we realize the network disk system. Disk system has the function of login module management, file management, friends sharing, sharing and transmission of public key list. And it also supports file copy, paste, cut, online preview, upload, download and file list refresh function.The successful development of disk system, solves the data storage needs of business users, provides an effective solution to meet the needs of enterprise management, a large number of documents and data. The system can also provide online file formats and preview file retrieval ability. Enterprise data, such as product development, financial and marketing, are likely to be generated by many different tools, thus having different file formats, which needs a unified file format conversionservice to support conversion of multiple file formats.
