Re: [IBMiOSS] [EXTERNAL] Re: Ports and routes needed to replace very large numbers of green screens

I'm pretty sure I've asked your question before. IIRC, the response was along the lines of "<shrug> If you run out of ports, just start creating virtual IP's."

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,
