Fair point. But people just love to over-complicate things and it is far more often that you come across absolutely ridiculous infrastructure monstrosities for very small business than that you come across the opposite.
I’ve found that career FOMO drives a lot of the desire to overcomplicate infrastructure.
It’s hard to look at job listings from prestigious companies listing K8s and other buzzwords as requirements without feeling some desire to add those buzzwords to your own resume.
