It's not at all unusual for demand to exceed the capacity of a single LAMP-powered server over time. You can take load off by moving your database to a second server, but when demand exceeds a two-server solution, it's time to think cluster. A LAMP cluster is not the Beowulf
How To Set Up A Load-Balanced MySQL Cluster
How To Set Up A Load-Balanced MySQL Cluster Version 1.0 Author: Falko Timme This tutorial shows how to configure a MySQL 5 cluster with three nodes: two storage nodes and one management node. This cluster is load-balanced by a high-availability load balancer that in fact has two nodes that use the Ultra Monkey package which provides heartbeat (for checking if the other node is still alive) and ldi
artima - Linux Clustering with Ruby Queue: Small is Beautiful
Ruby Queue software package lowers the barriers scientists need to overcome in order to realize the power of Linux clusters. It provides an extremely simple, economic, and easy-to-understand tool that harnesses the power of many CPUs while simultaneously allowing researchers to shift their focus away from the mundane details of complicated distributed computing systems and back to the task of actu
