Re: [Starlink] Starlink Digest, Vol 25, Issue 28

["David Fernández" <davidfdzp@gmail.com>]

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.

Regards,

David
