Service Bus messaging in the Azure portal
You can use the new Azure portal to create and manage Azure Service Bus messaging resources (namespaces, queues, and topics). Newly created namespaces on the portal are unique to Service Bus messaging—for now, you still need to use the Azure classic portal to create and manage Azure Event Hubs namespaces. Note that this change has no runtime impact on current namespaces, because they will be considered "mixed."
