KubeCon + CloudNativeCon North America 2024

The Kubernetes code now allows native construction of generic control planes, without container types and in new form-factors other than your beloved clusters, be it customized apiserver binaries or embedded into other applications. This talk gives an in-depth explanation of what a generic controlplane is, how to construct it, how to extend it with custom types and how to control which native Kube APIs like secrets, configmaps, etc. or mechanisms like resource quota or RBAC are available. Specifically, we will cover 3 variants: 1. single-tenant generic control planes using upstream Kubernetes. 2. multi-tenant generic control planes using kcp to scale horizontally in one process. 3. multi-shard and multi-region generic control planes with focus of backing SaaS services.
