	// an unexpected error occurred. Assumes that all nodes in the cluster are ready
	// and in sync with instance groups.

		nodes []*apiv1.Node,
		daemonSets []*appsv1.DaemonSet,

	// ScaleUpToNodeGroupMinSize tries to scale up node groups that have less nodes
	// than the configured min size. The source of truth for the current node group
	// size is the TargetSize queried directly from cloud providers. Returns
	// appropriate status or error if an unexpected error occurred.

}

Orchestrator is a component that picks the node group to resize and triggers creation of needed instances.
