This is highly interesting considering AWS invented the MicroVMs for lambda, yet node on lambda is dog slow (both in latency and throughput). I can traumadump on request. I bet they could use some of this tech especially since their use cases are often not too dissimilar (auth validation, rule checking etc)

  Firecracker is AWS tech, and was behind both Lambda & Fargate. I imagine it's all the enterprisey extras built on top that cause those issues.

    It is originally AWS, though we forked Firecracker ~4 years ago now and maintain an internal version with custom hypercalls (command-and-control from within the VM, POSIX-style fork, etc.) and a number of other features. We regularly pull patches and fixes from upstream Firecracker. You can read about the differences here:

    Weird time to advertise your product.

    When would you prefer they advertise? Seems entirely relevant.
    tomnipotent · 1790816395 · focus · HN ↗
    When they're contributing to the conversation. It's not relevant.
    fragmede · 1790816524 · focus · HN ↗
    How is it not relevant? In what way doesn't it contribute?

    It's on you to prove it does. In what ways does it contribute?
    fragmede · 1790817239 · focus · HN ↗
    We now know about their unikraft VM, whereas previous we did not.

    If only there was an HN guideline about not using the site primarily for promotion.

    You said they didn't contribute and weren't relevant. Whether their account primarily exists for promotion is a separate question.
