It was easy for us to configure our K8S nodes using this product because it provided all required components like kube master etc., In fact, we could set up the nodes within few clicks only. While working in rafay there were no issues but some of them are solved very soon after its notification. We have deployed few services which requires good availability. But so far nothing to complain about. I would say if you're looking for best managed service for your K8S setup then go ahead! They provide everything (from scratch) including management console, deployment agent, ingress controller, addon manager. Everything needed when deploying, managing or scaling cluster/service from outside. I like how easy it is to setup and configure the cluster itself. It is pretty straight forward and you can do almost all configuration settings from UI. While some of the commands are not so straightforward. You might have to dive into their docs or k8s slack if you don't find your answer there. I am solving my need for self service CI/CD and Kubernetes orchestration out of the box. With this product, I got everything I needed.
