Thanks and, yes it does!

We have a whole section in our documentation's guides section on example usecases with database:

https://docs.kraft.cloud/guides/#databases

They work exactly as you suggest, they scale-to-zero when no requests are made and data can be safely stored/transactioned in persistent volumes on the platform too.

Wow, you are responding to a poster who coincidentally has the same name as your main investor. Truly an amazing coincidence.

Both the twitter above and the HN user posted the link to findtime.fberge.com

Note everyone it's probably a big coincidence! These two posters most likely do not know each other. This exchange is totally legit.

If this applies to the dbs too then it's quite unusual and worth shouting about, I'm not aware of other providers which offer that!

Looking at https://docs.kraft.cloud/guides/mariadb/ with the Docker stuff in there I'd half assumed maybe DB instances worked differently from unikernel instances or something

Hi, Felipe from Unikraft here. Yes, it applies to DB instances too (all instances are the same on KraftCloud with respect to this).

Regarding multi-process, at present Unikraft has partial multi-process support: some multi-process apps work, others not yet -- we're hard at work completing this support.
