k8s is nice, yes. But, by its age, no more standardized now, than MySQL was 15 years ago.

k8s also adresses a very small portion of the market. If you have to scale, yes, you might need k8s. Chances are, you don't. Really.

I stopped counting the (supposedly big) customers that burnt themselves into k8s when they logistically need not to, and only brought organisational issues on them.
