Containers enable developers to package microservices or applications with the libraries, configuration files, and dependencies needed to run on any infrastructure, regardless of the target system environment. This means organizations are increasingly using Kubernetes not just for running applications, but also as an operating system.

In a classic 1983 paper , cognitive psychologist Lisanne Bainbridge drew attention to a curious irony: so-called “automated” systems were, in practice, usually attended by one or more human operators. The more advanced the system, she observed, “the more crucial…the contribution of the human operator.”
