I appreciate the thoughtful response!

These are all great points and I will review the article to see where it can be enhanced based on your feedback.

Some best practices are not followed in these examples, however the intent of the article was not to produce a production level setup, but rather provide others a jumping off point for their own implementation. There are some pieces as well that are opinionated or subjective, and one should always review their options before deciding on an architectural decision.
