Yes. Though I should emphasize that I'm using GKE. So it's zero config, zero ops. I am running a single n1-standard-2 node on GKE for a smallish app right now. Comes to 30-40 dollars a month all in (egress traffic, cloud storage, other services). I am working hard on getting people to use this app, and it's great to know that scaling will be best-in-class if I succeed.

But I stress it's not about the scaling. It's about the features even at a single node. I wouldn't be spending time writing this stuff had it not been revelatory for me.

PS. If you're not able to try it on GKE, there's also https://github.com/kubernetes/kops. GKE is great for trying, at least, though. Just get a cluster running and get rolling with the concepts. Then you'll know what it's all about. There isn't that much to it, and what there is to it is great and well documented with a great community.
