had master slave, had fault tolerant load balancing, had backup scripts, tested restore procedures. also had node upgrade procedures, and more.
it was more than just chef obviously but chef + any bare metal host environment gets you a large percentage of the way there. Tacking on specific aws services like route53 when necessary works too.
That's a great accomplishment in such a short period of time. I'm glad that you were able to save time and money by using another service. Thankfully, there are tons of options out there to suit every business' use cases.
