CVMFS
The CernVM File System solves the mirror image of the data problem: not moving data to
the software, but software to the compute. A POSIX read-only filesystem in user
space (FUSE), with content on ordinary web servers, mounted under /cvmfs, fetched
on demand and verified with cryptographic hashes. The design decision that makes it
deployable anywhere: outgoing HTTP connections only, so it walks through the
firewalls that stop every other network filesystem.
