Scaling DDS and MQTT with Eclipse Zenoh (sponsored by ZettaScale)
0Presented at EclipseCon 2023 in Ludwigsburg, Germany by Phani Gangula (Works for 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. This presentation will explain the challenges faced when trying to scale-out or scale-down DDS and MQTT in various application domains, including Robotics, IoT, and V2X, and illustrate how Eclipse Zenoh can be used, w/o any changes to your existing applications to overcome these challenges.
