LinuxCon Europe + CloudOpen Europe

Checkpoint-Restore is the technology that allows us to take a snapshot of running Linux processes and restore those processes in any other place and time. This opens various possibilities such as live migration, keeping HPC tasks safe from hardware problems, Cloud services load balancing and many other. Despite being very tempting feature to have, Linux lacked one for quite a long time. The Checkpoint-Restore In Userspace (CRIU) project is The One to make this technology real. This talk covers the project history, its dependence from and influence on the Linux Kernel and the Linux Kernel community and concentrates on usage scenarios that are now real with CRIU and that will be possible in the future. It will be interesting to anyone who knows Linux as user, but a certain level of system or kernel level programming experience would be required at some points.
