With the growing demand from the emerging IIoT, the traditional cloud-based computing model is now moving to the edge of the network.
Topic-based publication/subscription has been considered the most widely-used date-centric solution.
Energy is a precious resource, that goes without saying. As such, we should be using energy efficiently and effectively. But what does efficiency really mean?
One way of defining efficiency is with respect to the amount of work that is done with a unit of energy. This definition is sufficiently close to what is used in physics to characterize the efficiency of heat engines. It also can be used to reason about the efficiency of a messaging protocol – which is precisely the exercise we’ll undergo in this presentation.
MQTT and Sparkplug are the present and future of industrial automation. Together, they provide application decoupling, simplicity, and out-of-the-box interoperability. Given the lightweight nature of MQTT, you can deploy Sparkplug-compliant devices and software components across the whole Edge-to-Cloud continuum. You will find them not only in gateways and SaaS platforms but also in constrained devices relying on microcontrollers.
Eclipse Zenoh is a communication middleware designed to work across communication technologies, such as Ethernet, TSN, WiFi, Serial, OpenThreadX and BLE. It can operate at different geographical scales such as LAN, MAN and WAN, and in various topology configurations such as peer-to-peer, mesh, brokered and routed. Zenoh also provides a plugin mechanism to integrate with other middlewares like MQTT, DDS and HTTP, as well as to integrate with many storage technologies like InfluxDB, RocksDB, and MariaDB.
Amlen is a new Eclipse project that is the heir to a mature IBM product (IBM WIoTP Message Gateway) widely used ito publish live data/commands/event for IoT devices and webpages using the MQTT protocol.
We'll introduce Amlen, talk about its features and its future and talk about how people can get hold of Amlen and get involved in the project.
