The Linux Virtual Server (LVS) project www.linuxvirtualserver.org
is a load balancer which allows multiple requests to be balanced
amongst a set of backend machines. It works perfectly for readonly.
If clients write to the backend machines, then the updates have
to be propagated to the other backend machines, and you have to
do this outside LVS. If your usage is read mostly and you want
a low cost solution, then LVS will do what you want. If you want
a real parallel database, be prepared to pay lots of money to Oracle.
