The only thing I know about “good system design” is that it doesn’t exist in the abstract. Asking whether an architecture is good or bad is the wrong question. The real question is: Is it fit for purpose? Does it help you achieve what you actually need to achieve?

I could nitpick individual points in the article, but that misses the bigger issue: the premise is off.

Don’t chase generic advice about good or bad design. First understand your requirements, then design a system that meets them.
