Unicorn behind ELB, no nginx

view story

http://serverfault.com – If I understand Unicorn right (and in particular from their philosophy doc) it seems like Unicorn was really designed to operate behind a reverse proxy like nginx. My question is: can I drop nginx from my HTTP stack, considering we have an ELB at the top acting as the reverse proxy? I didn't find any issues on initial tests, but just wondering if anyone out there has experience on this front already. Thanks! (HowTos)
