Hello Stefano,
to your questions:
1.) To gather data from an existing OPC UA server (your server somewhere located on an IPC or PC) you need to have an OPC UA client running on netPI. You said you prefer to do that with Node-RED, correct? Then you need to install an OPC-UA Client into Node-RED. There is a node available you can install into Node-RED here https://flows.nodered.org/node/node-red-contrib-opcua. But you can also decide to use python also cause there is also a free OPC UA client available for python here https://github.com/FreeOpcUa/python-opcua. We cannot tell you which you want to prefer. It is up to you
2.) I have not collected any experience yet with Amazon Web Services. The only experience I collected was using the MS Auzre SDK from here: https://azure.microsoft.com/en-us/downloads/. A MZ Aure account you get for free 30 days within 5 minutes of work. So you can test it. I have made an example container at https://hub.docker.com/r/hilschernetpi/n...-showcase/ using the SDK to push some data to our MS Azure Account for a demo. But with the source code link of the container you can see how to install it into your netPI container.
3.)Well I would recommend to start with our example container https://hub.docker.com/r/hilschernetpi/n...-fieldbus/. It installs you can node-red and a fieldbus node extra to communication to our industrial network controller. But since node-red includes and installer for other nodes also, you can post install the OPC UA client and also the MS Azure Node-RED node https://flows.nodered.org/node/node-red-...re-iot-hub. But if I were you I would do my own container.
