If the cloud is on the satellite, half-hop. Starlink GWs are near Google Cloud datacenters. Blue Origin is on the mission to move Amazon Cloud to orbit, eventually, maybe, leaving the Earth as a garden to enjoy, without any industry on the surface (in a century, maybe). Kuiper will offer one hop access to Amazon Cloud, then half-hop. What seems a crazy idea today will be eventually implemented later, like Starlink (Teledesic failed, fingers crossed Starlink does not go bankrupt, although I would expect it be saved by Department of Defense, as Iridium was saved). As we were discussing recently, maybe starting with anycast DNS servers on satellites is a first step to consider, before embarking any other type of cloud servers.
