IBM bluemix is an IoT platform for Node-RED. I want to know what are the other platforms which can be used for the Internet of things in Node-RED.
Have you looked at the website?
There are links on how to get Node-RED running / access to Node-RED on three other cloud providers on the homepage
yeah got it Thanks.
Anything that can run Node.JS should be capable of running Node-RED. With some caveats around memory and other resource usage.
Node.JS runs on just about all platforms, even Android.
