Azure service bus namespace for Relay ?

Hello Team,

 

Reading new 70-532 book i can see:

 

A Service Bus namespace is a container for one or more entities, such as relays, queues, topics, event hubs, and notification hubs.

But under Service Bus i can see only queues and topics. I have configured relays and event hubs "outside" of service bus. Has is changed ?

 

Thanks,

Michal
