Seriously curious, don’t Firecracker VMs already run on EC2 instances under the hood when they host Lambda and Fargate?

Unfortunately I'm not at liberty to dive deep into those details. I will say that Firecracker can be used on bare metal EC2 instances, whether you're a public customer or AWS itself. :-)

I guess I should have peeked at the source code when I was there…

		No need, at least when I was there when the day was still one, before the pandemic. And well, Firecracker is open source. A few of the best technical presentations that I've watched were at a pre-SKO event. Nitro, Graviton and Firecracker. Great engineering pieces, the three of them.

Since I don't work for AWS I'm allowed to say that at the scale of millions/billions of microVMs you're better off running them on bare metal instances to avoid the overhead of nested virtualization.

		I used to work for AWS and I’m allowed to say the same thing. ;-)
