One could argue that you need the reproducible dev environments and CI to be solved BEFORE even start using Kubernetes.
So out-of-the-box support for blue/green deployments and fully versioned deployment history with trivial undo/rollbacks are of no advantage to you?
> Reproducible dev environments and CI you can get easily without Kubernetes, without having to add complex solutions for logging, profiling and other introspection tools.
I'd like to hear what you personally believe is a better alternative to kubernetes.
And by the way, Kubernetes does not support not requires distributed tracing tools not "logging, profiling, and other introspection tools". That's somethings entirely different and separate, and something that you only use if for some reason you really want to and make it your point to go out of your way to adopt and use.
In fact, distributed tracing is only a thing not due to kubernetes but due to you operating a distributed system. If you designed a distributed system and get it up and running somewhere else, you still end up with the same challenges and the same requirements.

If your product has a global audience who needs to CRUD stuff, caching and a single raspberry pi won't get you very far in the game.
If it's just an intranet stuff with a few hundred users and your front-end isn't very chatty then you're right, you don't need much.
