This is a heretical idea in some circles. Utter it and expect to be ostracized. In my case it’s cost a few job offers when I’ve suggested that a few python processes running under supervisor (e.g.) would be more than sufficient. It has its place but that point lies at a stage of development and sophistication far beyond where most cargo-cult users are currently.
I think it’s also probably because it gives people a “predictable” way to do things.
That being said I sometimes ask myself why we can’t constantly think KISS and YAGNI. Like, do we really need this level of abstraction and complexity? I’ve been “working” with k8s and I would probably fail any interview on it because I feel like I’m always googling my way through issues. I don’t even care anymore because I know for my own purposes outside of work, I keep my code and systems stupid simple.
And maybe this sounds cringey to some but I’m happy to write a few scripts on my own to handle deployments without needing to break my software into a thousand pieces. Single responsibility code using a few languages that are best suited for the task at hand (in my case it’s mostly node, elixir, go) that’s easy to break apart and ship separately is so nice. Why can’t we do the same at work?
