Java Message Service
Java Message Service (JMS) is a Java API that enables applications to create, send, receive, and read messages in a loosely coupled, reliable, and asynchronous manner. It provides a standard interface for message-oriented middleware (MOM) in Java-based systems, supporting both point-to-point (queues) and publish-subscribe (topics) messaging models.
Developers should learn JMS when building enterprise applications that require reliable, asynchronous communication between distributed components, such as in microservices architectures, event-driven systems, or financial trading platforms. It is particularly useful for decoupling producers and consumers, ensuring message delivery guarantees, and integrating with existing Java EE or Spring-based systems.
