A Research On Efficient Cloud Storage Strategy Considering User's Preference

The Cloud Computing has become the hot point of the computer and communications industry now.It's believed that the Cloud Computing will lead the third industrial revolution after the Personal Computer and the Internet.Cloud storage is a derivative services of the Cloud Storage,and got a great development in recent years.Cloud storage is a service that combined many technologies such as virtualization technology,distributed storage technology,data backup technology and so on.It takes the Internet as the carrier and provides users with services of data storage and access for a fee.Many research institutions and enterprises have carried on thorough research on the Cloud Storage,and the focus of the research are basic around the Cloud Storage cost,improving the quality of cloud storage service,improving the safety performance of cloud storage,etc.Based on the analysis on the previous work,this paper analyzes the user's behavior,around providing diffrent users with diffrent services,reducing duplicate data and setting up reasonable replications,and carries out a research which focusing on a kind of high efficient cloud storage strategy based on user's preferences.In this paper,the main research work are as follows:(1)This paper gives a comprehensive analysis and summary on the Cloud Storage which is a service pattern.This paper studies the latest research achievements in the Cloud Storage,and summarizes the advantages of Cloud Storage service mode and the existing problems,and puts forward an efficient cloud storage strategy which providing a train of thought for the next step.(2)Through the analysis of QoS preference,it is concluded that providing the same QoS cloud storage service for different users at the perspect of the Cloud Storage service provider and can effectively reduce the cost,also will not necessarily get high customer satisfaction.On this basis according to different user needs and preferences,this paper designs a user classification strategy based on QoS preference(3)This paper gives an improved data deduplication strategy based on previous classification strategy.And more detailed description of the main content of traditional deduplication and the basis process of a data deduplication are given.(4)In this paper,an implementation prototype system which consideration of user preferences and efficient cloud storage strategy is provided.Through expounding the mechanism of the prototype system,it demonstrates the efficient cloud storage strategy is effective.At the same time technical framework for the storage area is discussed in details.
