Additionally, your thought of having my company held hostage by a single devops person is terrifying. Now you need two of them, which is even more expensive.

It is a great way to bootstrap a company by saving on a salary (or two) that can honestly be engineered out for a lot of SASS businesses. It worked super well for us... and calling someone who did $80m in the first year deluded seems well, rude.

But, if you start off designing systems that scale on their own, you are much better prepared for when you do get some fast growth than dealing with hiring a good devops person (which is extremely hard, as they say.. all the good ones are taken).

At the end of the day, the actual elephant in the room is that django was the wrong choice. You end up having to go through a lot of contortions to make things work, as evidenced by the blog post. The architecture doesn't make things easy to spin up quickly... which creates a lot of bottlenecks. There are better cloud-based solutions.
