The Design And Implementation Of Full Replica High Concurrency Cloud Storage System

With the rapid development of computer technology and network technology,the application of cloud technology is gradually popularized in the aspects of network application service and enterprise server.The cloud storage has also gradually occupied a higher proportion in the information storage of today.In addition,as the Internet plays a more and more important role in people’s daily life,the cloud storage technology that relies on Internet technology has also expanded,and the demand for the operation of data information on the network server is increasing day by day.In all kinds of data processing technology,because of low price and high adaptability,the cloud storage technology is particularly prominent.At present,the cloud storage technology has been widely used.But with the continuous expansion of business,the concurrent performance and data security of cloud storage system need to be improved.This topic studies the backup function and high concurrent extraction performance of the cloud storage system.On the basis of the general cloud storage system,the full copy backup strategy and the high concurrency extraction are realized.Firstly,it introduces the foundation of cloud storage technology and the research status of home and abroad.Based on this,it leads to the design of full copy high concurrent cloud storage system in this paper.Then it focuses on the analysis of the basic theory of cloud storage used in this paper,including the principle of distributed storage,the HDFS file system and the application principle of SQL database;then,it designs a full copy and high concurrent cloud storage system structure,including the full copy.The general structure design of the cloud storage system,the design of the full copy scheme,the design of the high concurrency extraction scheme and the design of the database,and then verify the function and performance of the cloud storage system designed in this paper.The test results show that the concurrent extraction performance of the cloud storage system designed in this paper can be increased linearly,and can meet the development trend of the concurrent extraction demand;the full copy backup scheme can effectively improve the security of the data.From the result of the final operation of the system,the full copy high concurrent cloud storage system designed in this paper has good security and high concurrency.It can meet the growth requirements of the future data storage service well,and provide data support and help for further research on cloud storage technology.
