Red Hat Load Balancer

The Load Balancer is a set of integrated software components that provide for balancing IP traffic across a set of real servers. It consists of two main technologies to monitor cluster members and cluster services: Keepalived and HAProxy. Keepalived uses Linux virtual server (LVS) to perform load balancing and failover tasks on the active and passive routers, while HAProxy performs load balancing and high-availability services to TCP and HTTP applications.
