It absolutely is -- to be fair the previous versions of Unikraft weren't quite easy or maybe ready for wide consumption, but they took some funding and at the very least their marketing and documentation massively improved.

Hugely impressive.

A little weird that they say "no cold start" versus... "minimal cold start".

Cold starts in milliseconds != no cold starts, though I get it -- marketing is marketing and it's not wrong enough to be egregious :)

That said, super excited that someone has built a huge complex database like Postgres on Unikraft.

Been a while since I kicked the tires on Unikraft but looks like it's time to do it again, because this isn't the only software that could use this model, given an effective unikernel stack.
