PubSubModelle
PubSubModelle refers to a family of models and patterns for publish-subscribe messaging architectures, emphasizing decoupled producers and consumers, asynchronous communication, and scalability. It covers brokered and brokerless implementations and is commonly used in event-driven systems and microservices.
In PubSubModelle, components include publishers, subscribers, and a delivery mechanism such as a message broker or
Architectures vary. In a central broker model, a broker receives all messages and forwards them to interested
Common protocols and formats support PubSubModelle, including MQTT, AMQP, or HTTP transports, and data encodings such
Benefits include loose coupling, scalability, and resilience, enabling real-time event processing, data pipelines, and microservice communication.
Trade-offs include eventual consistency and higher coordination complexity, potential ordering challenges across partitions, operational overhead for
The pub-sub paradigm has roots in message-oriented middleware of the 1990s and has evolved into modern event
