If you google the following you will gain some perspective:
multiple node.js apps on same port
Each app doesn't appear to require its own port necessarily.

Hi Justin,
Yeah, that's what I'm getting at.
If you look at Node.JS tutorials, they almost always create a simple app that is hosted in its own Node.JS web server (i.e., the web server functionality of Node.JS). If I use this model, and treat each web service as an independent Node.JS app running in its own web server, then I potentially end up with many hundreds of ports running Node.JS web servers. I know there is routing in Node.JS frameworks like Express. But then I get back to my question: do I want one Node.JS server with large numbers of Express routes in an initial gateway app? Or is there some balance between number of Node.JS web servers and Express routes that I should be aiming at? If so, what would be recommended? What's the target?
We would never do a big-bang approach where we actually tried to convert all of our green screen apps at once. But, once we get started, the number of conversions will grow over time. I would like to have plan in place for how we will manage them. I don't want to wait until it becomes unmanageable, then realize we painted ourselves into a corner and have to re-code everything.
Thanks,

I share Kelly's concern about ports. How do people handle it? If I magically converted all our 5250 apps to Node apps, I'd have thousands of ports listening.
