+> Deleting the Azure IoT Operations instance in the Azure portal doesn't remove the dependencies that were created when you deployed Azure IoT Operations. To remove these dependencies, use the `az iot ops delete --name <INSTANCE_NAME> --resource-group <RESOURCE_GROUP> --include-deps` command described in the Azure CLI procedure.

 ### [Azure CLI](#tab/cli)
 
 Use the [az iot ops delete](/cli/azure/iot/ops#az-iot-ops-delete) command to delete the entire Azure IoT Operations deployment from a cluster. The `delete` command evaluates the Azure IoT Operations related resources on the cluster and presents a tree view of the resources to be deleted. The cluster should be online when you run this command.
