Google long ago released Snappy Start, a tool for snapshotting processes, saving the full state to disk, so new instances can be launched faster. This is a more general Checkpoint-Restore capability than V8's impl and a bit different, but definitely somewhere in the same field of computer technology.

Seems also related to CRIU, which does something similar, but for the purposes of live migrating a process from one host to another. https://criu.org/Main_Page

Yeah I probably should have lead with CRIU. It's been a longstanding ongoing project of excellence. A lot of people who work or worked (unsure of breakdown) on OpenVZ have been cranking on this for many year.

Work from the CRIU crew started getting upstreamed almost exactly four years ago, breaking some initial resistance to the tech needed for CRIU- https://mobile.twitter.com/__criu__/status/58727373960931328... https://criu.org/History

It's interesting the breakdown in sell- CRIU is a swiss army knife of a tool, whereas Snappy Start and V8 Snapshots seem targetted and marketted largely towards fast "initialization" concerns.
