I had always thought that the cost of an Event Hub was associated to each individual event hub. Looking at the costs of scaling however, it am starting to think that the billing of event hubs is more about the number of throughput units against the service bus namespace. Is the latter correct?
For example, if I have two event hubs in a namespace that process relatively low numbers of records (so no additional usage/storage costs), am I paying ~$23/mth or ~$46/mth?
