[erlang-questions] Serve PHP/Python scripts behind Erlang

[Nathaniel Waisbrot]

It depends on what you mean by "efficient" :-) Some methods that I've worked with (Python only)

- Python uses Flask+Gunicorn to serve requests, Erlang makes HTTP calls to it
  You get to customize the request as much as you want in Erlang, the coupling is loose, it's easy to do black-box tests on the Python service alone
- Python uses Flask+Gunicorn to serve requests, Nginx reverse-proxies to Python and to Erlang, P&E don't talk to each other
  Nginx is good at forwarding connections, the coupling is loose, it's easy to do black-box tests on either sub-service alone
- Erlang calls Python through ErlPort (http://erlport.org/ <http://erlport.org/>)
  Faster than a network connection, tighter coupling, you manage queueing and pooling yourself
