I can only see this being effective if the Nginx instance isn’t also responsible for reverse-proxying the frontend traffic, and if it’s not running on the same server as the frontend or backend (ie. decoupled from the infrastructure serving the stack). Haven’t looked at the article yet but I’m assuming they would recommend provisioning the infrastructure with that decoupling, or it wouldn’t make much sense.
Atheist here. Extraordinary claims require extraordinary evidence. Atheism is merely about trusting what’s been proven, or has some evidence backing the claim that can be verified without doubt. Being agnostic is being indecisive about everything, even things that are completely made up.
