I like how this article clearly and articulately states the reasons it gains to benefit from Kubernetes. Many make the jump without knowing what they even stand to gain, or if they need to in the first place - the reasons given here are good.
Helm, for instance, is a great time saver for installing software. Often software will support nothing but helm. Ease of deployment is a good consideration. Their points on networking are absolutely spot on. The scaling considerations are spot on. Killing/isolating unhealthy containers is completely valid. I could go on a lot more, but I don't see a single point listed as invalid.
