About HAProxy

HAProxy is the reference open-source load balancer: it distributes incoming traffic across multiple application servers, checks their health (health checks) and switches over automatically in case of failure (failover). Renowned for its performance and reliability, it powers some of the largest platforms on the web.

On your ServOrbit VPS instances, HAProxy lets you scale horizontally: add servers behind the load balancer to absorb the load, with no software cost — it's entirely free.
