Ok, this is a very wide topic but I will try to touch some corners in the event somebody will need such ideas. This will be a series of articles that I will write as time permits.

What will be covered in these series:

- what is a cluster? http://www.at-byte.com/technology/web-optimizations-part-1-what-cluster
- why would i need a cluster? http://www.at-byte.com/technology/web-optimizations-part-2-why-would-i-n...
- web server optimizations
- tools? mysql vs mysql-cluster, http servers, nfs server, redundancy for high availability (heartbeat and nfs server, syncing) , webmin can help?
- more will be added depending on idea availability :)

Yes, this will be all about linux servers and all those free goodies out there. Expensive tools is not really my target here.

stay tuned
