It's from the value of :class:`insights.combiners.cloud_provider.CloudProvider.cloud_provider` id (str): The ID of the cloud instance type (str): The type of the cloud instance. Different cloud providers have different illustration of the `type` and `size`, here for this Combiner, we treat the `type` and `size` as the same.
