Hands-On Industrial Internet of Things

The edge

We can develop our edge with different technologies and frameworks. In Chapter 10, Implementing a Cloud Industrial IoT Solution with AWS and Chapter 12, Performing a Practical Industrial IoT Solution with Azure, we will learn about AWS Edge (Greengrass) and Azure Edge. We will also develop a simple Edge MQTT with the AWS SDK, Azure SDK, and GCP SDK. To develop a simple edge to access the OPC UA server, we can use Node.js and the OPC UA client (http://node-opcua.github.io/). In this simple exercise, we are going to use a graphical interface called Node-RED.
