Open Stack

There's a ton of info available at https://swiftstack.com/openstack-swift/. Specifically, take a look at https://swiftstack.com/openstack-swift/architecture/ for how Swift solves some of these issues.

You might also find the info at http://swift.openstack.org useful, especially http://docs.openstack.org/developer/swift/admin_guide.html.

For more info on failure handling, see https://www.youtube.com/watch?v=mKZ7kDDPSIU where I went through several failure conditions and show how Swift recovers from them. There's also a much older blog post at https://swiftstack.com/blog/2012/09/13/how-openstack-swift-handles-hardware-failures/.

While it might not be the academic paper you're looking for, this should give a good groundwork of info. If you have other questions, feel free to ask.

And it seems that it is being handled by the concept of Rings;however, what is a Ringbuilder? is it a central service or a distributed protocol? what if it fails? How rings info and its changes are shared among different nodes?
