•
1 j'aime•451 vues
The document summarizes a presentation about integrating Node-RED with open source technologies. Node-RED is a browser-based flow editor that allows wiring together hardware devices, APIs, and online services to build IoT applications. It can be run on edge devices like Raspberry Pi or in the cloud. The presentation covers Node-RED's open source development, popular nodes, deployment options including on IBM Cloud, and demos of connecting Node-RED to IBM Connections.

- 2. Social Connections 14 Berlin, October 16-17 2018 Node-RED makes it easy to wire together the Internet of Things. It provides a browser-based drag-drop UI for creating flows of events and deploying them to the runtime. The light-weight runtime, built in node.js, is ideal for edge-of-network environments or running in the cloud. It can be easily expanded to take add new nodes to the palette – taking full advantage of the node package manager (npm) ecosystem Introducing Node-RED

Paul Morrison at IBM in the early 1970’s • A network of asynchronous processes communicating by means of streams of structured data chunks • Each process is a black box – it doesn’t know what has come before it, or what comes after it; it just acts on the data it receives and passes the result on Flow-based Programming https://en.wikipedia.org/wiki/Flow-based_programming
