Now we have seen the architecture and the deployment models for Kubernetes-based hybrid clouds. Please note that it is still in pre-release at the time of writing this book. This method of building a hybrid cloud gives us the most advantages in this scenario.
Kubefed is still in beta, is mainly tested on the GKE, and is one of the best choices for use in production right now. The main points to keep in mind while designing a federated cluster are: the state of all applications resides in the actual cluster, the federation supports about 100 clusters, and each cluster supports approximately 10000 nodes.
Clusters can fail independently of each other, so failures are easy to manage. In the next few chapters, we will deal with operating the hybrid cloud and some of the concepts involved in this.
