Since the end of the free money era, a lot of people are rightly questioning the microservice/k8s/cloud-native model that requires you to run an operation team of 20 people and has a baseline cost of 200k$/year for a cluster that doesn't do anything yet.
I have worked in multiple orgs that standardized on Kubernetes as end users. Those numbers are coming from my real life experience. If we include all costs it is actually probably way higher than 200k per cluster.
