Managed Kubernetes vs Self-Managed: EKS/AKS/GKE vs kubeadm vs k3s vs RKE

Managed Kubernetes vs Self-Managed#

The fundamental tradeoff is straightforward: managed Kubernetes trades control for reduced operational burden, while self-managed Kubernetes gives you full control at the cost of owning everything – etcd, certificates, upgrades, high availability, and recovery.

This decision has cascading effects on team structure, hiring, on-call burden, and long-term maintenance cost. Choose deliberately.

Managed Kubernetes (EKS, AKS, GKE)#

The cloud provider runs the control plane: API server, etcd, controller manager, scheduler. They handle patching, scaling, and high availability for these components. You manage worker nodes and workloads.
