CernVM-Filesystem is a network file system based on HTTP and optimized to deliver experiment software in a fast, scalable, and reliable way. Among the other users, LHC experiments rely on CernVM-FS. Files and file metadata are aggressively cached and downloaded on demand. Thereby the CernVM-FS decouples the life cycle management of the application software releases from the operating system. CernVM-FS is included in CernVM, however it can also be used outside CernVM. To download CernVM-FS please go to the download page, the technical report on CernVM-FS is available here, and the review of CernVM-FS from the security perspective can be obtained from this page.
