This "sample" should be the gold standard for every AWS service

Kudos to this team!

This repo so fully implements the best practices of setting up RDS using CloudFormation, that all resource types should use it as a model.

As a customer of AWS and implementor of AWS on behalf of clients, I should be able to source complete public CloudFormation templates that implement the best practices of running a given infrastructure type.

I sorely wish I had a template repo exactly like this(auto-rotating passwords, VPCs, bastions, keys, permissions, everything) but for DocumentDB.
