is there a source for this? a place where people list their reference architectures and deployment scales? i'm not a deployer but as an outsider, i've found that there isn't a lot of transparency in regards to how projects have been made to scale. maybe this is a side effect of OpenStack being hard as hell to use, but it seems configurations are the secret sauce people use to sell so we have a lot of failure stories (bottom-end constraints) in the community rather than successes (upper-end constraints). are there a collection of fully transparent deployers out there to be our 'production' baseline? to help vet scalability? just CERN? -- 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
