@USNetizen -- You're right...I should have clarified that I want to know how to get an entire stack up and running, although I don't trust myself to do this unassisted.
I'm just surprised at how few resources there are that explain what it takes, and I hope that someday soon, healthcare startup CTO's will be referred to clearly documented open source solutions that are fairly fool-proof, rather than paid-for services (@sebst). Amazon's compliance page is unfortunately uninformative (@byoung2).
