One of the things I things I've seen in many organizations is DNS basically being shit across the various environments.
Records get added over the years, layers over layers of indirection, no zones or zone delegation for different parts of the infrastructure, and general unwillingness to burn it to the ground and 'do it well'.
It's a bold claim, but I think that if 10% of the attention organizations give to cloud buzzwords, containers etc was given to proper DNS setup a lot of internal problems would go away.
I understand that DNS is critical, and thus the unwillingness to touch it, but it's one of those things that can only get worse over time with no attention.
What do you think about this?
