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?
