[Chicago] Thoughts on Virtual Hosting

[Jordan Bettis]

Apache will work, but these days the "standard" way to setup a wsgi 
python service is to start nginx and use it as a gateway, then have 
Flask running in a pool of wsgi servers like gunicorn. So your setup 
would look like this:

internet -> nginx (http gateway) port 80/443 -> gunicorn (Flask app) 
listening on a pool of localhost only ports, say 5000-5010.

Nginx then does the load balancing between workers, terminating TLS, 
etc. You can do this with apache too of course, but it's pretty heavy 
for this architecture.
