I work for a company that routinely deploy very large scale software to airlines/airports/rail companies around the world. Millions of lines of mission critical server and mobile/browser/desktop client code. We do it without the cloud, without micro-services, without Kubernetes etc. Just straight forward good old fashioned client/server monoliths. It’s simple. It works. The reality is that 99% of people who think they need Kubernetes don’t actually need it. Almost all problems in software development are caused by the developers themselves. Not by the actual business problems.
