IP Restrictions on Service Bus Standard and Basic
One thing that has frustrated me for some time with Azure Service Bus is that the network security features, such as Private Endpoints and Service Endpoints, are locked behind the premium SKU, which has a significant extra cost. I believe security features should not be locked behind expensive SKUs and should be available to anyone using the service, as they are with most other Azure services. This results in either paying extra for the premium SKU just for these features or running the cheaper SKU without the additional security features.
