alt Hacker NewsHard disagree - only because if you didn't have DNS you would have something else in its place. But, we understand DNS _very_ well.
People, services, machines, etc need to "dial" canonical-somewhere. Whatever does the canonical management is the piece that when it breaks everything breaks.
Doesn't matter if it's DNS, EIP rotation, some HA proxy, whatever. It'll break.
It's actually that DNS is so well understood that it doesn't fail more often.
So no, DNS is for IT Infra.

That is absolutely true. I believe that a solution where you provision a text file with an updated ip address or /etc/hosts file is inherently simpler, less risky and easier to recover from, although I admit I don't explicitly state this in the article.
