"Cluster" means different things to different people and/or
applications, but loosely, clusters can be grouped into High
Availability and High Performance.
Do you want a high availability active/standby cluster? Or a high
performance load balanced cluster? The latter is much harder to
implement properly. The high availability active/standby style of
clustering is described in the wiki article Greg just posted.
