When choosing distributed systems platforms to work with, k8s vs. rolling your own orchestration isn’t the decision anyone is making. It’s k8s vs cloud vendors that want your money in exchange for the headaches.
Honestly running your own control plane is not that much harder than using something like EKS or GKE. The real complexity that the grandparent was talking about is all the tweaking and configuration you have to do outside of the control plane. Eg the infrastructure and deployments you’re building on top of Kubernetes and all of the associated configuration around that. In other words, whether you use EKS or hand roll your own kube you still have to solve node auto scaling. Load balancing. Metrics/observability. DNS and networking. Ingress. Etc etc etc.
