The large deployment team (https://wiki.openstack.org/wiki/Large_Deployment_Team) meets regularly and presents architectures at the summits and ops mid cycle meetup ‘show&tell’ sessions. I can remember presentations from Walmart, Paypal/eBay, Rackspace and Yahoo! recently. The LDT etherpads also contain a lot of information. This is then regularly put into the ops manual (http://docs.openstack.org/openstack-ops/content/architecture.html). > >-- >gord > >__________________________________________________________________________ >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
