Scaling DDS and MQTT with Eclipse Zenoh (sponsored by ZettaScale)
DDS and MQTT are two commonly used technologies in IoT, Robotics, V2X, Aerospace, etc., that take diametrically opposite approaches to implement the pub/sub abstraction. DDS embraces a peer-to-peer model, in which applications communicate directly with each other. On the other hand, MQTT adopts a hub-and-spoke architecture in which a central broker mediates communication between applications. Both technologies have shown scale-up/down and scale-out limitations.
