The whitepaper of Piranha and Piranha HOWTO are available at Red Hat web site. The RPMS and SRPMS of piranha can be found in the RedHat 6.1 distribution, or can be downloaded from the ftp.redhat.com site.
Ultra Monkey is a complete open source server farm solution for linux, providing high availability and load balancing. See the Ultra Monkey site for more information.
Keepalived implements a framework based on three family checks: Layer3, Layer4 & Layer5. This framework gives the daemon the ability of checking a LVS server pool states. When one of the server of the LVS server pool is down, keepalived informs the linux kernel via a setsockopt call to remove this server entrie from the LVS topology.
