I'd say it is possible to run Darwin on AWS, but I have never tried. FreeBSD runs well, so we know that any OS with drivers will boot on AWS. They're Apple aft

I'd say it is possible to run Darwin on AWS, but I have never tried. FreeBSD runs well, so we know that any OS with drivers will boot on AWS. They're Apple after all, so they can build macOS to boot from a standard environment - UEFI, kernel that doesn't check the copy prevention string on SMBIOS, etc. Us, mere mortals, are more restricted, as we don't have the keys of the kingdom.
