Recommended External Web Server To Host Teams Tab?

Hi,

I've created a Teams tab and am hosting it locally using ngrok + node.js. This is working fine. However, I would like to host it on an external web server. What is the recommended web server to use? Can it be hosted with Apache Tomcat? If so, is there any documentation and/or examples of how to do this? I can't seem to get it to work with Tomcat and I have not found any information on this topic.


Thanks,
George
