Thoughts on CloudViews: Communal Data Sharing in Public Clouds

Summary:
Public clouds have lots of bandwidth, so it is easier to share data between services in the same cloud. The paper raises the issues in sharing and what the security options are. They maintain the view that data is owned by the service rather than the data creator. They allow services to specify which portions of their data is accessible to other portions. But once data is shared by one service with another, it becomes owned by the other service and can do whatever it likes with it. They don't provide federation of resources and assume a few large public clouds.

This was a quick read and needs to be read again.
