That article is magic. Here is the most important part:

“But what about when we scale to 100,000 users?”

“Then we’ll have the revenue to hire a dedicated infrastructure team. Right now, we have eight engineers and we’re spending 60 hours a week managing Kubernetes instead of shipping features.”

That excerpt clicks so many of the Paul Graham boxes. Common sense aside I am also a huge fan Docker Compose. It is stupid simple on a hard to fathom scale.
