Highly amateurish take if you call shell spaghetti a Kubernates, especially if we compare complexity of both...

You know what would be even more bad? Introducing kubernates for your non-Google/Netflix/WhateverPlanetaryScale App instead of just writing few scripts...

Hell, I’m a fan of k8s even for sub-planetary scale (assuming that scale is ultimately a goal of your business, it’s nice to build for success). But I agree that saying “well, it’s either k8s or you will build k8s yourself” is just ignorant. There are a lot of options between the two poles that can be both cheap and easy and offload the ugly bits of server management for the right price and complexity that your business needs.
