I'd hoped that's exactly what comes across in my top-level comment. I've been lucky enough to be at or near the coalface of PaaS for most of its life, both as a basic engineer getting my head around deploying CRUD apps on Heroku and its ilk, and as an architect contemplating the designs of various PaaSs. My little sketch of a story is how I saw things unfold. Don't get me wrong, Kubernetes is amazing, it's everything we hoped for, I use it and recommend it. But the only thing that's innovative about it is that it's backed by a big player, so we can rely on at least a few years of active development and mindshare. But from my perspective, the great innovation, the thing that really changed the game, was The 12 Factor App manifesto. That's what deserves a documentary made about it, because it's just a text document, but it inspired so much.
