File Redundancy

1 Introduction with the progress of science and technology, the environment complexity of IT industry is increasing day by day, more http://www.aliyun.com/zixun/aggregation/13546.html "> It budgets are used to maintain the infrastructure and maintain the normal operation of the application, rather than to better meet customer needs. The emergence of the cloud seems to bring new hope to people, so some people make such a prediction-the future cloud era. 2 Cloud Architecture System Design 2.1 cloud architecture concept and special ...

Research on large data encryption algorithm based on data redundancy technology the main research contents and innovations of the thesis of Wang Misty in North China Water Conservancy and hydropower University include: 1. General encryption model of large data and the principle of encryption technology. Based on the systematic study of the basic characteristics of large data and the general encryption model, this paper deeply analyzes the technical principle and advantages and disadvantages of the four kinds of large data encryption schemes based on modern cryptography, bioengineering, attribute based and parallel computing. 2. A large data redundancy algorithm based on Bloom filter technique is proposed. According to large data information ...

Recently, a question was raised on Quora about the differences between Hadoop Distributed file systems and OpenStack object storage. The original question is as follows: "HDFS (Hadoop Distributed File System) and OpenStack object Storage (OpenStack object Storage) all seem to have similar purposes: to achieve redundant, fast, networked storage. What are the technical features that make the two systems so different? Is it significant that these two storage systems eventually converge? "After the question was raised, soon ...

Cloud computing storage optimization based on stacked file system Guo Wan Zhangxiaofung The redundancy caused by a large number of virtual mirrors in the cloud environment will result in lower resource utilization and the use of deduplication to ease the need for storage space and network bandwidth, but there are also problems in handling performance degradation. In this paper, a cloud storage optimization scheme based on stacked file system is proposed. The scheme utilizes a scalable file system to store a small amount of modification information of a user to a virtual instance on a read-write disk, storing the virtual image in a reading disk, saving only a small amount of modification information for the virtual instance at a time, without saving ...
