This is embarassing. I'm getting a 502 Proxy Error.

Well. That means that HAProxy is still up when the backend servers aren't. "embarassing" isn't the terminology I'd use in this case.

I believe they use nginx. Traditionally ELB has been the most featureless LB's you'd ever encounter. That's in direct contrast with HAProxy. Truly a pain point with AWS IMO.

ELB has features that nginx does not (health checks for one), and does not take advantage of many features that nginx does have. On the other hand, the feature set of HAProxy (1.5 branch, now "released") matches remarkably closely.

Check out Tengine, a Nginx fork made by Alibaba guys ;)

How come this is a news if 1.5.1 has already been released on June 24th?

June, even. I'm still interested, though. Fitbit uses haproxy but I set up my development machine with nginx because of SSL. It probably doesn't make a difference, but I'll still feel better when I can easily make my dev setup more closely mirror production.

From what I recall, the SSL functionality was in haproxy for a while now. Some time ago, when I was doing research if I have other options for SSL enabled LB other than Nginx, I found the information that haproxy has such support included, but for some reason I decided to go with Nginx anyway.

What about SSL? HAProxy supports SSL offloading.

I didn't investigate deeply; I'd never heard of haproxy prior to Fitbit. Someone from site ops told me they use nginx + haproxy but it would be easier for me to just set up nginx.

This article does sound to me like SSL support in haproxy is brand new: http://seanmcgary.com/posts/using-sslhttps-with-haproxy

I have the sneaking suspicion that Amazon's Elastic Load Balancer is based on HAProxy (and has been tracking the 1.5 series in development for some time). Nothing particularly evidentiary, but it's a glass slipper that fits very snugly.

Mostly, HAProxy. In contrast, the AWS-clone Eucalyptus IaaS platform uses HAProxy for ELB functionality, mimicking AWS ELB functionality [1]
