Regarding aistore the recommended prod configuration is kubernetes, which brings in a huge amount of complexity. Also, one person (Alex Aizman) has about half of the total commits in the project, so it seems like the bus factor is 1.

I could see running Aistore in single binary mode for small deployments, but for anything large and production grade I would not touch Aistore. Ceph is going to be the better option IMO, it is a truly collaborative open source project developed by multiple companies with a long track record.
