Managed Kubernetes doesn't eliminate complexity, it shifts it out of sight. In this talk, we look behind the curtain of Managed Kubernetes to show the architectural building blocks that enable Managed Service Providers (MSPs) to deliver production-ready clusters for customer workloads.

We will walk through different patterns for control plane hosting and node lifecycle management, comparing practical approaches from open source projects like Gardener, Kamaji, and Cluster API. This includes analyzing the tradeoffs of the individual approaches.

The core of the talk is a deep dive into Gardener. Through a live demo, we demonstrate how Shoot clusters are managed by Seed clusters, how control planes run in dedicated namespaces, and what actually happens during real lifecycle operations.
