I just fell on the post today. I am the one who wrote the article... I'm a bit terrified by the comments haha. But that's a way to learn and improve stuff.

Thanks for your support in the middle of this.

To answer your question: our dev environment is iso to staging and production with AWS accounts for each developer. The cost is close to 0. Deploying and testing a code change takes seconds. Deploying and testing a config change however is still a little bit longer for sure...
