Kubernetes and co. Is an effective way to aggregate tens to thousands of machines, promote best practices through primitives (autoscaling, rollouts, disruption budgets, traffic shifting, monitoring, etc.) And promote the use of immutable infra in orgs. 15 years ago doing this stuff well took at least 10x the engineers it does today and you would have had to cut yourself on every sharp corner that these tools make smooth. At my last company (a startup) I (1 person) bootstrapped infra for a continuously deployed web app that distributed scientific workloads across 10k+ cores of compute in 6 months with no prior experience running large clusters. 15 years ago that would have been impossible. Frankly it wasn't really difficult enough to be fun with these tools.
