LVS is a group of tools that do a lot of different things, the two
that you are interested in are:
- heartbeat - provides failover if you have two nodes (active/active
- ipvsadm/ldirectord - provides load balancing (ie. http(s) load
balancer in front of multiple web servers)

network and we handle a lot of traffic. Some we're using for http(s)
traffic, others smtp/pop/imap, others mysql (read only queries off
replicas). There's no end to what what you could use heartbeat or
ipvsadm/ldirectord or both for. Both packages can be installed from
