This Azure Service Bus Architecture Diagram represents the Azure Service Bus. This is an enterprise message broker with message queues and publish-subscribe fully managed topics (in a namespace). This Azure Service Bus Architecture Diagram also depicts various communication mechanisms such as queues, issues, and relays. Messages will be saved until they are read. One person only receives each message in Queue. A topic may have multiple subscriptions for different receivers. Subscriptions have the option of receiving messages based on parameters. Messages from Queues and Topics can be accessed via REST APIs or Service bus-defined messaging APIs. Because Azure Service Bus is a fully managed service, the Azure team will handle scaling and availability.
