Managed Kubernetes Responsibility Matrix: Who Manages What?

Managed Kubernetes responsibility flow

For every area, record provider scope, the team owner and the test record.

How should the responsibility matrix be used?

For each row, write the provider scope, the internal accountable role and the pre-production test. The split follows the written service scope.

Evaluate version and upgrade readiness separately

Supported version differences between Kubernetes components are governed by the official version-skew policy, while provider-supported cluster versions and upgrade workflow are service-specific. Test deprecated APIs, admission webhooks, CNI or CSI, ingress controllers and monitoring add-ons in staging. Rehearse node drains, PodDisruptionBudgets and rollback boundaries before the maintenance window.

Separate security ownership by layer

Apply least privilege, separate service accounts and recurring access reviews to API access and RBAC. Clearly assign ownership for secret storage and rotation, pod security settings, image provenance and scanning, admission policy, NetworkPolicy and audit records. A managed control plane does not automatically secure an application image or an unsafe ClusterRole definition.

Do not confuse cluster recovery with application-data recovery

Control-plane resilience or a provider backup does not guarantee that PVCs, databases, object storage and application configuration can return to the intended recovery point. Inventory where state lives, define an application-consistent backup method and time a restore into a clean environment. RPO and RTO become meaningful only with the scope and result of that test.

What does VKE provide automatically in cluster operations?

VKE is the open-source Kubernetes engine developed by vMind. It automatically provides node-level autoscaling, load balancers and storage classes.

The templates are for sharing ownership, progress and check steps with your team.

FAQ

Frequently asked questions about Kubernetes

Does managed Kubernetes transfer all operations to the provider?

No. A provider may own some control-plane tasks, but applications, images, access, policy, data and recovery still need explicit team ownership.

Who patches worker nodes?

The upgrade plan records who owns node-image and operating-system updates, the schedule and the replacement method.

Does a Kubernetes backup include application data?

Not automatically. Cluster objects, PVCs, databases and external object storage may require different methods. Document scope and validate it through a clean-environment restore.

What does the application team own during a Kubernetes upgrade?

The application and platform team tests deprecated APIs, webhooks, add-ons, images, PodDisruptionBudgets and application behavior, and joins maintenance and rollback planning.

Does managed Kubernetes imply GPU-node support?

Managed Kubernetes on its own does not mean a GPU node. VKE automatically provides node-level autoscaling, load balancers and storage classes.
