sõnumibrokker

Sõnumibrokker, also known as a message broker, is an intermediary software component that facilitates communication between different applications or services. It acts as a central hub that receives messages from producers and delivers them to consumers. This architectural pattern is commonly used in distributed systems to decouple applications, making them more resilient and scalable.

The primary function of a sõnumibrokker is to enable asynchronous communication. Instead of applications communicating directly, they send messages to the broker, which then stores them until the intended recipient is ready to process them. This asynchronous nature allows applications to operate independently without waiting for each other, improving overall system responsiveness.

Sõnumibrokers support various messaging patterns, including publish-subscribe and point-to-point. In the publish-subscribe model, a producer sends a message to a topic, and all subscribers interested in that topic receive a copy. In the point-to-point model, a message is sent to a specific queue, and only one consumer retrieves and processes it.

Popular examples of sõnumibrokers include RabbitMQ, Apache Kafka, and ActiveMQ. These technologies offer features such as message persistence, guaranteed delivery, and load balancing, which are crucial for building robust and fault-tolerant applications. By abstracting the complexities of inter-application communication, sõnumibrokers simplify the development and management of modern software systems.
