Hey Kurt, we're big fans of fly.io! Happy to chat about tech sometime, I think you folks are using firecracker for a similar use-case? Drop me a line at colin@

  Hi Colin, congrats on the (re-)launch! Fellow SUS 2019 graduate here. I know layerci's tech precedes snapshot support in Firecracker [0], but are snapshots similar to layerci's magic or there's still a significant way for snapshots to go before it can be on par with layerci's tech? I ask because I remember you mention layerci uses techniques (from how Linux hibernates PCs) which are good enough for tests and staging but not production; [1] whereas Firecracker obviously can't rely on such tech so there must be key differences? Thanks. [0] https://github.com/firecracker-microvm/firecracker/blob/master/docs/snapshotting/snapshot-support.md https://github.com/firecracker-microvm/firecracker/blob/mast...

    Firecracker is definitely heading in the same direction we did with their "diff snapshots", though they don't let you create a COW chain yet, so there's still quite a bit of development to be done on that front.

      Firecracker snapshots to device mapper could be pretty cool. We don't do much with snapshot/restore but we do a _lot_ with device mapper. It's pretty badass.
