Managed Kubernetes service¶
A managed Kubernetes service is a hosted offering where the cloud
provider operates the Kubernetes control plane — and, in stronger
variants, the data plane too — on behalf of the customer. The
customer interacts with the Kubernetes API and deploys workloads
using standard K8s object types (Deployments, Services, etc.), but
does not own the etcd cluster, the API server, the scheduler,
Kubelet patching, or (in nodeless variants)
Node capacity planning.
Spectrum¶
| Tier | Control plane | Data plane | Example |
|---|---|---|---|
| Self-managed K8s | operator | operator | kubeadm, kops |
| Managed control plane only | provider | operator | vanilla EKS, vanilla AKS, vanilla GKE |
| Managed data plane | provider | provider (with operator-owned Nodes) | EKS Auto Mode, GKE Autopilot |
| Nodeless | provider | provider (no Node object) | Fly Kubernetes (FKS), Fargate-on-EKS |
Fly.io's "blessed path" framing¶
Fly.io's FKS beta post positions FKS as their "blessed path"™️ to using Kubernetes backed by Fly.io infrastructure" — a deliberately opinionated managed service:
We take care of the complexity of operating the Kubernetes control plane, leaving you with the unfettered joy of deploying your Kubernetes workloads.
Fly's nodeless composition pushes beyond EKS / GKE / AKS defaults by also eliminating the Node / capacity-planning surface, via the Virtual-Kubelet + Fly Machines substrate.
Operator responsibilities by tier (typical)¶
- Self-managed: etcd HA, control-plane upgrades, Kubelet patching, Node autoscaling, CNI operations, CSI driver choice, cluster DNS operations.
- Managed control plane: Node autoscaling (Karpenter / cluster autoscaler), Kubelet AMI upgrades, CNI/CSI choice.
- Managed data plane: maintenance-window consent, Pod Disruption Budgets, workload compatibility with managed-AMI refreshes.
- Nodeless: workload-level concerns only (Pods, Services, HPA…); provider owns everything below the Pod.
