configure a ubuntu virtual machine - to serve a node js app exposing a node-red page for a lab
This video documents the process of setting up / configuring a simple Linux (ubuntu) virtual machine for a specific requirement. So please feel free to debug using Google and while the exact details vary, broadly you can set up node-js ecosystem and python or use a similar configuration to experiment with AWS EC2 or Azure, deploy simple node JS or Python apps & share with friends, or demonstrate research.
