 Seldon Core v2 can integrate with Azure Event Hub via Kafka protocol.
 
+```{warning}
+You will need at least `Standard` tier for your Event Hub Namespace as `Basic` tier does not support Kafka protocol.
+```
+
 ```{warning}
 Seldon Core v2 creates 2 Kafka topics for each pipeline and model plus one global topic for errors.
-This means that total number of topics will be `2 x (#models + #pipelines) + 1` which will likely exceed the limit of `Basic` and `Standard` tier in Azure Event Hub.
-See quota information [here](https://learn.microsoft.com/en-us/azure/event-hubs/event-hubs-quotas#basic-vs-standard-vs-premium-vs-dedicated-tiers).
