Docker and Kubernetes both immediately made sense to me when I found them. They both obviously addressed pain points I've had before and were easily recognizable to me. (Docker lets me share server applications with their environment, and Kubernetes makes sure I always have N replicas of that Docker image running on my hosts.) What are the short and sweet issues that service meshes and control planes each solve? I see a bunch of things listed on Kuma's page, but I thought those were what service meshes did.
