Azure Service Bus
Azure Service Bus is a fully managed enterprise message broker service in Microsoft Azure that enables reliable cloud-based messaging between applications and services. It supports both publish-subscribe and point-to-point communication patterns, offering features like queues, topics, and subscriptions to decouple systems and handle asynchronous operations. It provides advanced capabilities such as message ordering, dead-lettering, and session management for complex enterprise scenarios.
Developers should use Azure Service Bus when building distributed applications in Azure that require reliable, scalable, and asynchronous communication between microservices, cloud services, or hybrid environments. It is ideal for scenarios like event-driven architectures, workload distribution, and integrating disparate systems where message durability, ordering, and transactional guarantees are critical, such as in e-commerce order processing or IoT data pipelines.
