StackSync: Architecturing the Personal Cloud to Be in Sync
In the last few years, the authors have experienced a rush of online storage services with a complete set of tools for file syncing, sharing and collaboration. Unfortunately, commercial personal cloud solutions, e.g. dropbox, box, sky-drive and the likes, are closed and proprietary, which supposes a serious impediment to progress research, also forcing people to be stranded into locked systems. In this paper, they argue about the necessity for an open-source personal cloud framework that provides scalable file synchronization and sharing, and that allows anyone to easily implement and evaluate new ideas.
