Sõnumibrokeri

Sõnumibrokeri, often translated as message broker, is a software component that facilitates communication between different applications or services by enabling them to exchange messages asynchronously. It acts as an intermediary, decoupling the sender from the receiver, meaning that the sender does not need to know the location or availability of the receiver, and vice versa. This decoupling is crucial for building scalable, resilient, and loosely coupled distributed systems.

The primary function of a sõnumibroker is to receive messages from producers (applications that send messages) and store them in a queue or topic. Consumers (applications that receive messages) can then retrieve these messages from the broker at their own pace. This asynchronous nature allows producers and consumers to operate independently, improving overall system performance and reliability. If a consumer is temporarily unavailable, messages will be stored by the broker until the consumer is back online.

Common use cases for sõnumibrokerid include task queuing, event streaming, and inter-service communication in microservices architectures. They handle tasks such as distributing data to multiple interested parties, managing background processing jobs, and ensuring that messages are delivered reliably, even in the event of network failures or application crashes. Popular examples of sõnumibrokerid include RabbitMQ, Apache Kafka, and ActiveMQ. These systems offer various features like message persistence, delivery guarantees, and sophisticated routing capabilities to meet diverse application needs.
