Abstract:
Cloud resources nowadays contribute an essential share of resources for computing in high-energy physics.
Such resources can be either provided by "private clouds", academic infrastructures that allow running virtual
machines instead of batch jobs, or by public clouds such as Amazon EC2 or Google Compute Engine.
In any case, users need to prepare a virtual machine image that provides the execution environment for the
physics application at hand. CernVM is a small and versatile virtual machine base image that runs on a variety
of different cloud infrastructures and can be easily adapted to support typical physics workflows.
It is used, for instance, to run LHC applications in the cloud, to tune event generators using a network of volunteer
computers, and as a container for the historic software environment of the decommissioned ALEPH experiment.
