Deep dives
The Importance of CERN VM and VMFS
CERN has developed the CERN Virtual Machine (CERN VM) and Virtual Machine File System (CVMFS) to tackle the immense data processing challenges presented by high-energy physics experiments such as those conducted with the Large Hadron Collider (LHC). With data generation reaching exabyte levels due to significant upgrades and the addition of more powerful experiments, traditional methods of data handling and software distribution became insufficient. These tools enable a globally distributed computing model that helps manage data from approximately 150 sites around the world. The ability to package complex software stacks within a single virtual machine image allows for greater efficiency and easier synchronization across various data centers.
