I've been using unikraft (https://unikraft.org/) unikernels for a while and the startup times are quite impressive (easily sub-second for our Rust application).

What drove you to choose that over something like containers?

[droelf]

Yeah, boot time, isolation (proper VM vs containers), and ease of use on a larger Hetzner box.

[m00dy]

shorter cold-boot times.

[ATechGuy]

Fast boot up means nothing if your agent/app is slow at runtime (due to virtualization tax or QEMU emulation). Fast boot up is a PR term, which can easily be optimized for compared to designed a better virtualization layer that performs near-bare-metal.

Wouldn't faster boot times mean that scale-out can be done on-demand? Whether this is preferable or not over poorer runtime performance is up to the domain, no?
