> If you mean why not only use nginx Yes, this is what I meant. I originally wrote a SaaS app that was hosted through Apache and ended up putting NGINX on top of it for the aforementioned reasons. But eventually testing showed that removing Apache just made the whole thing a whole lot more manageable. I have friends with similar anecdotes. Just putting NGINX in front from the get-go would have saved a lot of tech debt.
