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?
