Hi Ildiko,

If this helps, the latest TripleO architecture for edge computing is
documented in our deployment guide:


The architecture consists of a centralized control plane, and distributed
sites for compute nodes (DCN) and if necessary, persistent storage with
Ceph. Each site has an independent Ceph cluster serving only that site, as
well as associated cinder-volume services plus HAProxy for some
HA/failover. The storage configuration takes advantage of the Glance
multi-store and associated management commands feature. The improvements
around storage might be nice to highlight since I believe they were added
specifically for the edge use case.

There is a downstream blog post done by Red Hat about storage at the edge,
but it is entirely based on the upstream OpenStack TripleO, Glance and
Cinder projects:

There is also an earlier post about management of distributed sites with

HTH, let me know if I can provide any further details.
