Load balancing in EC2 with Nginx and HAProxy

We wanted to setup a loadbalanced web cluster in AWS for expansion. My first inclination was to use ELB for this, but I soon learned that ELB doesn’t let you allocate a static IP, requiring you to refer to it only by DNS name. This would be OK except for the fact that our current DNS provider, Dyn, requires IP addresses when using their GSLB (geo-based load balancer) service.

Rather than let this derail the whole project, I decided to look into the software options available for loadbalancing in EC2. I’ve been a fan of hardware load balancers for a while, sort of looking down at software-based solutions without any real rationale, but in this case I really had no choice so I figured I’d give it a try.
