On one server their will be following applications running:
- OpenOffice
- Tally72
- Scribus/Pagestream
There are max 50 PCs on one server. Instead of one server I want to use normal PCs approx 2-3 by doing clustering. I have heard about google. They have used normall PCs with cluster.
Probably what he wants is multiple application servers loaded with OO, tally, Scribus. Load of ~50 users should be balanced by 2-3 such servers. So a load balancing cluster is needed for boot servers and applications servers.
Please see if http://www.linuxjournal.com/article/9097 fullfills your needs.
