One stable Kafka cluster is worth more than 1000 kubernetes clusters (for free) to me. Kubernetes to me is kind of useless. I don't use it for the sake of learning it. What's the point ? I write code for human, to serve real benefit/profit from business standpoint. I build value and trust based on what i delivered, not from what i "want to learn". Currently, i go all in for unidirectional architecture. Think redux all the way, not just for frontend. The point here is, it's the architecture that's drive business profit, not Kubernetes. Kubernetes is not your architecture.
