Flow Based Programming • Invented by J. Paul Morrison at IBM in 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

From the Edge to the Cloud Easily installed on the default Raspberry Pi image, Node-RED can be used out of the box to begin creating IoT applications Available in the IBM Cloud catalog as a quick start application, it takes moments to create cloud applications that combine services across the platform. Easily installed on other cloud platforms.

Other Input Nodes HTTP – Act as an HTTP endpoint; great for building RESTful services IBMIoT – Receive messages from an attached Watson IoT Platform Also can receive from Websockets, MQTT (pick your own broker), TCP and MQ Light

Slide 17

Slide 17 text

Other Output Nodes HTTP Response; required as the final node when the input comes from an HTTP Request IBMIoT – send events out to the attached Watson IoT account Twilio – send SMS messages via the Twilio service IBM Push – Send Push notifications to mobile devices Also can send requests through TCP, UDP, MQLight, WebSockets.
