Virtualization has significantly reduced the cost of creating a new virtual machine and cheap storage allows VMs to be turned down when unused. This has led to a rapid proliferation of virtual machine images, both active and dormant, in the data center. System management technologies have not been able to keep pace with this growth and the management cost of keeping all virtual machines images, active as well as dormant, updated is significant. In this paper, the authors present ImageElves, a system to rapidly, reliably and automatically propagate updates (e.g., patches, software installs, compliance checks) in a data center.
