Why? Do you also see any purpose in hopping on one foot to work instead of driving there?
I don't understand what leads people like you to try to move goalposts to pretend something is harder than it is or needs to be.
I've set up quite a few kubernetes clusters on my own, and relied on the clusters I've built for production services at both startups and big tech companies. I've done quite a bit with both local storage and network storage via Ceph.
I am not German, and I have never been to Germany. If we're trading wild speculation about personal details, I think you could use some ambition and self-confidence.
You come off as very arrogant who believes he knows everything, some humility would suit you well, but I think all pseudo smart Germans are like that.
