There's a lot more that can happen differently there. Docker doesn't hide all the details of the filesystem, kernel version, or the like. With EC2 instances you're still running a kernel that has a lot of moving parts of its own.

I'm sure that's true, but it's not a statement directly about consistency.

It's a lot harder to get consistency out of a non-unikernel system running on EC2 - e.g. IME the linux boot/hardware probing process can behave nondeterministically before it even starts running your user program.
