Load balancing at Github: Why ldirectord? | Anchor Web Hosting Blog

Some comments on Github’s blog post “How We Made Github Fast” have been asking about why ldirectord was chosen as the load balancer for the new site. Since I made most of the architecture decisions for the Github project, it’s probably easiest if I answer that question directly here, rather than in a comment.
Why ldirectord rocks

VoiceXML and CCXML Developer Site

This article will describe how to set up software load-balancing and failover for web applications (in this case for a bigger installation of VoiceObjects: 4 machines with each 8 productive instances plus one staging instance). Two additional machines will be hosting the failover / load-balancing solution.

The load should be evenly balanced (round-robin) between the instances. In the beginning it is not planned to make a health-check on individual machines or instances.

The failover capability will be reached by having the actual productive machine claiming a virtual IP (VIP) from the network. In case of a failure this VIP will be passed to the backup machine.

All traffic will reach the machine from Port 80. Thus a port-forwarding for the productive load and an additional URL rewriting for the staging load is needed.
