Seeing a bunch of folks in my mentions saying “TIL Google doesn’t use Kubernetes” and ... I’m surprised there are people who think Google *does* run on k8s. Even GKE (Google’s hosted Kubernetes offering) runs on Borg, which afaik, is far more sophisticated and battle-tested.

Without knowing the subject in detail, I dare to claim that Borg is far more purpose-built solution than #kubernetes ever will be, and kubernetes have now already slipped far from the vision of the original authors.

You can just ask the original authors, they're still here and still involved with Kubernetes

Let's do that then, right here and right now! @jbeda @brendandburns @cmcluck @bgrant0607 @thockin How far has #kubernetes slipped from your original vision? Does it look like a system that you wanted it to be? Or has it also grown to unfavorable direction?

There's no "unfavorable" direction. It has fulfilled much of the original vision but it has done SO MUCH more. It's still (comparatively) immature, and it suffers tech debt and scope creep and tragedy of the commons, but none of that is unexpected or uncommon.

Agreed. Where k8s is is a synthesis of some of what we all imagined when we started plus a ton of ideas and sweat and passion from others. No one person can plan something like this out. It really is emergent.

I think comparing Borg and Kubernetes isn't really the point, they're built with very different goals in mind. I think in general brush-strokes Kubernetes is exactly what we imagined. I think in the details it contains many many things we didn't imagine.

Is there a nice comparison between the two available somewhere?
