I have a very simple question. Nginx does reverse proxy buffering for HTTP servers like Gunicorn and Unicorn. However if I have a Elastic Load Balancer (offered by Amazon Web Services also known as -- ELB) is there any point in running nginx in front of my app server?

 Request----> ELB -------> NGINX-------> UNICORN/GUNICORN HTTP SERVER
nginx amazon-web-services unicorn gunicorn amazon-elb
