Node-red and Raspberry pi 3

Hello, I don't know if this is the right place. I currently have a node-red application running on a Raspberry pi and would like to provide access to this application not only internally within my network but externally access to the Internet. Would anyone have any suggestions on where to make it available and how to do it?
