I have to imagine that Fargate on Windows doesn't use Firecracker though, right? Firecracker needs kernel level changes to work properly, and the open source version doesn't let you run anything but Linux.
I have no idea how it works under the hood. Knowing what I know about Firecracker from watching the publicly available videos, I was shocked and thought it would never happen.
On the other hand, CodeBuild has supported Windows containers for years and at least CodeBuild for Linux is based on Fargate, so the service team figured something out. (I had to figure out how to word that. I can’t say “they figured it out” since I work for the same company. But I couldn’t say “we” since I’m so far removed from any service team in the consulting department that it would be disingenuous)
