Distributed Messaging is a communication method used in computer systems where messages are sent between different components or services across a network. This approach allows various applications to exchange information efficiently, even if they are running on different servers or locations. It helps in building scalable and resilient systems by decoupling the components, meaning they can operate independently. In a Distributed Messaging system, messages are typically sent to a central broker or queue, which then distributes them to the appropriate recipients. This ensures that messages are delivered reliably, even if some parts of the system are temporarily unavailable. Popular tools for implementing Distributed Messaging include Apache Kafka and RabbitMQ.
