Earlier quoted context omitted.

OK I had missed the kata containers blurb in the FAQ, thanks for pointing it out. In fact the tweets make my point: we are all so blinded by new shiny releases that we forget their highly incremental nature.

Sure, there are going to be some people that are excited by the fact that something seems new or just because it is written in Rust, but jessfraz and bcantrill certainly don't fall into those categories. They have a lot of experience with Operating Systems, VMs and containerization and I don't get the impression that they are eaisily impressed by shiny things. Note that they all work for or worked for AWS competitors…

As a QEMU developer, this is very exciting. Even though there are some differences in the approach to the device model, they are not important in the grand scheme of things and in principle there is no reason why QEMU could not serve the same uses as Firecracker. It's just like Linux runs on anything from 16MB routers to supercomputers, and it means there is a lot that we can learn from Firecracker.

In fact we are considering integrating a more secure language than C in QEMU, even though we're just at the beginning and it could be C++ or Rust depending on whom you are talking to. :) It's possible that this announcement could tilt the balance in favor of Rust, add it would be great if QEMU and Firecracker could share some crates.

The crosvm and Rust have me intrigued. I was hoping for something like this since I saw the first hints of Rust showing up in ChromeOS in crosvm. A compare/contrast with Kata Containers would also be interesting. Their architectures look similar. (Kata Containers [1] being another solution for running containers in KVM-isolated VMs, that has working integrations with Kubernetes and containerd already. Not affiliated,…

The devops training site katacoda.com will be interesting to watch. They spin up and tear down _so_ many VMs, their cloud bill must be monstrous. Firecracker is much leaner, so they would save a lot of cycles by spinning up Firecracker over Kata.

Katacoda has nothing to do with Kata Containers...

I'm not sure how you can make any of the conclusions anyway, unless you know a lot of seemingly private details about how KataCoda is implemented.
