One item the DevOps mindset missed was reproducibility. Fast feedback loops in spirit tell to have a way to know what’s wrong but it doesn’t tell how to reproduce it as you have layers and layers where your code is run. So, you are in a spot of I kinda know what’s going on but I have no way to reproduce it because:

- the application has hardcoded paths.

- the service discovery isn’t dynamic

- the branching strategy doesn’t account for edge cases.

- the build process doesn’t account for edge cases.

- and many other things that are related to bad practices.

I recall an old boss saying he wanted stable dev environments which sounded an oximoron. I’ve always aimed to have an environment where I can reproduce a desired behavior wether is a faulty or not.
