I was looking to use Apache Traffic Server for its reverse proxy functionality, but I also need it to load balance across clusters of servers. The documentation mentions load balancing, but I cannot find any details about it. Could someone please confirm one way or the other, and if it does support it, could you please provide a pointer to the documentation.

    I have concluded that ATS does not support load balancing. I have used NGINX instead. This worked really well. – Lee Jensen Sep 11 '12 at 19:22

You will need mod_proxy & mod_proxy_balancer, per the docs

  • Can you use Apache Server Mod files with Traffic Server? – Lee Jensen Jul 10 '12 at 18:47
  • ah, after a look at [Apache Traffic Server](http://trafficserver.apache.org/) I see the docs are sparse as you suggested, but imagine this software is intended to run in front of a set of Apache servers. Not sure what you mean exactly by 'Apache Server Mod'. – quickshiftin Jul 10 '12 at 18:54
  • I suppose that you could put Traffic Server in front of a Apache servers with mod_proxy_balancer running on them, but that seems like an unnecessary complication unless you are also using Traffic Server's caching ability. What I was hoping for is that Traffic Server supported load balancing directly, but I don't think that it does. – Lee Jensen Jul 16 '12 at 18:21

Out of the box, Apache Traffic Server only supports round robin load balancing using dns to resolve to multiple origins.

There is a plugin which offers more advanced balancing capabilities though:
