I think a lot of Amazon's internal tooling is sort of "unpublished" - I've not found a great reference for a lot of the really excellent dev support they had.
The AWS story is particularly interesting because a lot of the internal setup I was doing at the time was on old fashioned metal. There was an internal project called Move to AWS (MAWS) that encouraged using newly-developed integrations with the AWS systems that the public was using.
In other words, AWS lived alongside old-fashioned provisioning practices up until even the early 2010s.
