With Azure Service Bus you can decouple app components so they don’t need to communicate directly - instead messages flow through a central hub that manages queues, topics and subscriptions. The service is fully managed by Azure, so you don’t need to provision or maintain your own messaging infrastructure.
It supports both point-to-point needs (queues) and publish/subscribe scenarios (topics + subscriptions) where multiple consumers can receive the same message. That makes it particularly suitable for enterprise scenarios that require delivery guarantees, ordering and durable messaging.
If your traffic grows significantly or you require extreme isolation and high availability, the Premium tier offers dedicated resources and guaranteed performance.
