Perhaps these are the pictures Jim was referring to? https://www.dropbox.com/s/255x1cao14taer3/MVP-Architecture_edge-computing_PTG.pptx?dl=0# I'm involved in some TripleO work called the split control plane: https://specs.openstack.org/openstack/tripleo-specs/specs/rocky/split-controlplane.html After the PTG I saw that the split control plane was compatible with the type of deployment discussed at the edge WG session in Denver and described the compatibility at: https://etherpad.openstack.org/p/tripleo-edge-working-group-split-control-plane > See the picture and table here: > https://wiki.openstack.org/wiki/Edge_Computing_Group/Edge_Reference_Architectures#Overview > >> Now, I don't have really great suggestions.

In split control plane there's a deployment method for deploying a central site and then deploying remote sites independently. That deployment method could be used to deploy Core/Hub/Edge sites too. E.g. deploy the Core using Heat stack N. Deploy a Hub using stack N+1 and then deploy an Edge using stack N+2 etc. John >> >> I'd be very interested to hear your ideas. >> >> Dmitry >> >>  https://etherpad.openstack.org/p/tripleo-edge-mvp >> >> _______________________________________________ >> openstack-sigs mailing list >> openstack-s...@lists.openstack.org >> http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-sigs > > __________________________________________________________________________ > OpenStack Development Mailing List (not for usage questions) > Unsubscribe: openstack-dev-requ...@lists.openstack.org?subject:unsubscribe > http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev __________________________________________________________________________ OpenStack Development Mailing List (not for usage questions) Unsubscribe: openstack-dev-requ...@lists.openstack.org?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
