Research And Implementation Of Cloud Platform Based On VHD

Under the traditional model,the personal or companies need special software and hardware equipments.When the information is more important and the capacity is bigger than others,they may need the specialized maintenance personnel.With the development of network technology,service providers through the clustered application,grid technology and distributed file system to make sure the network of the large capacity storage devices and for storage service through data network to out the data in the online storage space which is provided by servicers.For normal user,it will saving the cost of disk construction for software and hardware,and also to ensure the ability of user data storage.Therefore,once the Cloud Storage service come to the market,the customer is more and more larger.However,with the rapid development of Cloud Storage service,it also exposed many problems.Firstly,each Cloud Storage service is individually,there is no unified platform for future development.Secondly,Cloud Storage service platform need a lot of loyal customer,this limited its development.Finally,the users need a quickly method to know Cloud Storage services.As all of above problems,we design the network function based on the windows on the VHD(virtual hard disk)to come true the network functions.In this paper,the main work is as follows:First research Cloud Storage platform in view of the current situation of the Cloud Storage development,then choose the implementation technology of Cloud Storage platform.under the current situation which is the platforms have more choice without closed communication,we choose VHD which has larger customer as the standard of the Cloud Storage platform.Based on the VHD technology,the Cloud Storage platform can run on the any platform(including windows)which support VHD,which makes the system has strong compatibility and transportability.Secondly discuss the overall architecture of Cloud Storage platform.We discuss Cloud Storage platform architecture from the physical structure,network topology structure,logical level,software module,software flow.Through the definition and architecture,we can understanding the platform through the hardware foundation,networking mode,operation model,customer demand,software architecture and other aspects.finally using the software engineering method to implement the Cloud Storage platform.Based on the general software engineering method,to detailed analysis market demand of the Cloud Storage platform,through the selection to the Cloud Storage platform,to select the VHD format as the system protocol,then design the detailed architecture for the Cloud Storage platform,and on this basis to design the modules for the future,then to coding and testing,and finally,to complete the core code of the Cloud Storage model for C/S model.Under this architecture,platform not only let VHD as standard common interface of file access,to solve the problems between Cloud Storage platform,but also connected the customers of windows to make them to be easier to understand the system.
