Not All Managed Kubernetes Are Created Equal: A Deep Dive into Control Plane Architectures
summary
Compares control plane patterns (virtual, hosted, dedicated) and evaluates tradeoffs using Gardener, Kamaji and Cluster API; demonstrates a live Gardener demo that creates a Shoot with two worker nodes, shows the Seed clusters hosting dedicated control-plane namespaces, and the gardenlet reconciling ControlPlane and Infrastructure CRs. Claims Gardener runs thousands of customer clusters at scale, relies on provider extension controllers for cloud-specific resources, and scales by adding more seeds under a management (virtual garden) cluster, not by sharing etcd.
