We built something into our registry that squashes layers of an image into a compressed rootfs archive. Edge nodes map an image back to one of these files when launching an app. This cut launch time for large images in remote regions from tens of seconds to a few hundred ms. Much of that infrastructure is actually running on fly itself!
