Cloud Storage Access Gateway

Cloud storage services (CSSs) such as Dropbox, Google Drive and Microsoft´s OneDrive are more and more popular. For users, they can access and store their data through the Internet at any time and at anywhere. On the other hand, Web service providers (WSPs) can reduce their costs on devices storage by using CSSs´ API to access users´ cloud storages and managing their data indirectly. Although this method is convenient, it still a problem that each CSS has its own connection method of cloud storage´s API and WSPs must spend additional time understanding them for operating and development. In this paper, we propose a CDMI-compliant cloud storage access gateway to solve Dropbox, Google Drive and OneDrive three different connection methods of APIs. By using our CDMI-compliant cloud storage access gateway, WSPs can easily develop Web services supporting accessing users´ data in their cloud storages and users can manage their own data in their trusting CSSs.
