I’m not sure I’ve seen unanimous agreement in an HN comment section before so that’s nice I guess.

But to address the article in a simple environment dns _just_works_. I’ve never once had an issue with bind. It’s incredibly simple and stable and easy to understand when working with within a small environment without much churn and enables other technologies to operate in an expected way because it’s the standard. ACME, kerberos, sshfp, many more are enabled by DNS. Sure maybe you can kludge some of that back together with hosts but I’d rather not just to replace one of the most stable services that exist.

DNS does start to get more complicated in massive environments but that’s just a reflection of the environment. Using ansible to manage /etc/hosts across hundreds or thousands machines with churn will not be less complicated to manage than dns.
