VCF 9.0 explicitly states: “The VKS exposes three layers of controllers to manage the lifecycle of a VKS cluster,” and then enumerates those layers. The first layer is the set of components that integrate the workload cluster with Supervisor-backed resources, including aCloud Provider Plug-inthat integrates with the Supervisor and enables infrastructure integrations such as persistent volume requests being passed to the Supervisor (which is integrated with Cloud Native Storage). The second layer isCluster API, described as providing “declarative, Kubernetes-style APIs for cluster creation, configuration, and management,” driven by resources that represent the cluster, the VMs making up the cluster, and cluster add-ons. The third layer is theVirtual Machine Service, which provides a declarative API for managing VMs and associated vSphere resources and is used to manage the lifecycle of the control plane and worker node VMs hosting a VKS cluster.
Therefore, optionAis the only answer that matches the three lifecycle controller layers defined in the VCF 9.0 documentation.
