Well, O3b MPower (MEO satellites) is offering independent one hop
dedicated access to the (Microsoft Azure) cloud as "killer
application". 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.

Where do I even start? The lack of substantial bandwidth between space and
ground? The extra latency between ground and space compared to terrestrial
cloud, especially as terrestrial cloud edge can move much closer to
customers when space can't? The fact that every LEO satellite is both a few
100 km from every customer and out of the customer's range depending on when
you look? That low temperatures in space don't mean superconductive chips
that produce zero heat, and that that heat is difficult to get rid of in
space? That generating power in space is orders of magnitude more expensive
than on the ground?
Just because Starlink can provide a service somewhere between DSL and low to
medium grade fibre to a few million around the globe it's not "done". Even
with 10x the number of satellites and a couple of times the current capacity
per satellite, Starlink isn't going to supply more than a couple of 100
million at best, and that's not even accounting for growth in demand from
IOT...
