Based on my own experiences, one of the most disappointing elements of devops is their lack of understanding how things work. They run to GitHub and pull other peoples recipes to build out certain environments. Even when they build automation from scratch, they miss tons of core OS level tunables and rather than adjusting those, they'll just add more servers to the mix.

I worked at a place that had an elastic search cluster with 30 nodes, because they kept hitting open file limits, when 8 servers could easily handle the traffic with basic tuning.

You could replace "devops" in your first paragraph with "developers" and it would still make sense. Everybody is out there grabbing stuff from GitHub and shoving it into their projects. Most technical folks today don't really know how a computer works, they poke at it until it does what they want and call it a day.

And I would say that your specific example is a failing of that team, not "DevOps" as a whole.
