I can't speak for Parse, but I've come up with something similar in the past. Nginx/HAproxy as a combo is far more flexible than the ELB alone, you might want to use it for rate limiting, better load balancing algorithms, better logging, tweaking headers, handling errors, or controlling buffer sizes for example.

- tcwc 14y agoTrue, though the ELB also does some simple buffering of HTTP requests.
