The Design And Implementation Of Distributed Enterprise Network Disk System Based On Cloud Storage

With the deepening of the company’s business, and the documents number and variety decreasing, it is difficult to manage the data, besides, the cost of storage is high, resulting in the increasing importance of unified file storage management. Massive file management requires the usage of cloud computing mass data processing and distributed storage technology, providing secure and reliable online document management, which can promote enterprise business process optimization, improve operational efficiency and reduce operating costs. This thesis studies the design and implementation of enterprise network disk system which is based on the distributed cloud storage. The main works, including:Firstly, this thesis introduces the research status of cloud storage technology, and analyzes the framework of the current mainstream of cloud storage system and the key technology of implementation. Distributed cloud storage architecture is discussed, including the current mainstream of file system and the storage architecture to realize it. Besides, this thesis introduces the framework of relevant technologies in this system.Secondly, a three-tier system is based on B/S architecture which is a design principle. Giving full consideration to the flexibility, versatility and efficiency, this thesis determines the whole system, and gives the framework design of a distributed enterprise cloud network disk storage system, which includes user interface layer, Web system of the front/back ends, business logic layer and data storage layer. It gives the design of business logic layer, including function modules of basic service, document service, administration panel and system management, which are all realized. And then, in the view of storage layer, this thesis carries on a detailed implementation of three modules which are storage, load balance and data encryption, including the design of database.Finally, some functional and performance tests are made which can show that the system can meet the design requirements. The system has already been put into use in a state-owned enterprise. The system is running stably and reliably, achieving the expected design target.The system uses cloud storage technology to provide files storage and backup of daily work for the company employees, achieving the usage, sharing and collaboration of information, protecting the security of company documents. Gradually, the distributed cloud storage application system will. become an important data storage platform.
