I'm curious what their load balancing layer looks like. There's alot of interesting options. (Disclaimer: I've worked in the CDN and the storage space in the past) If their load balancer is smart enough it can call the dispatcher, and make use of something like https://zaiste.net/nginx_x_accel_header/ https://zaiste.net/nginx_x_accel_header/ to figure out where to forward the request. Unfortunately this still requires uploads be proxied through the dispatcher. You could get crazy and involve a CDN (akamai or cloudflare or fastly) that could do some smart logic, especially if you can emit your dispatcher as a lookup table that's updated frequently. I don't know what bandwidth costs would be for that though. Probably high. It's an interesting problem space and I'd love to talk to these folks about it.
