Cloud native containerized applications heavily rely on resiliency. When a container dies, it is restarted. When a node is under evacuation, containers it hosts are killed and started
elsewhere. But there are occasions when checkpointing and restoring a container would be more effective. Long-running jobs, stateful applications, function runtimes for serverless computing, all could benefit from checkpoint-restore and container migration. And for some applications, the absence of these capabilities could be a show stopper for moving from virtual machines to containers.

With CRIU, the industry standard container migration tool, it is possible to migrate containers and reboot hosts without losing network connections, results of long-running calculations, or the state of
in-memory databases.

In this talk, we present the container migration technology and its applicability to various use cases.


Mike Rapoport

Researcher, IBM
Mike has lots of programming experience in different areas ranging from medical equipment to visual simulation, but most of all he likes hacking on Linux kernel and low level stuff. Throughout his career Mike promoted use of free and open source software and made quite a few contributions... Read More →
