hi, everyone.
i have a question about server architecture.
i want to to study about how to setup the servers serving huge projects like wikipedia, google searching service,.etc.
But i didn't know what kind of books or where on the Internet have that information.
I've seen the server description and server architecture diagrams of wikimedia.
They have squid cache servers, database server, web server, nfs servers, and search server.
Where can i find the information about how to build servers for such huge projects?
and i saw that they put some servers as loading balancer?
it is done through what? programs?that hold some users' request?

I really want to know about the server hardware architecture.

thanks

I would suggest you get a few thousand dollars before thinking about that.

double post mistake, please delete

You mean the books are expensive?or that understanding the server structure is an empirical process? if i want to know how it works i'll have to learn from a working experience?

thx

I remember having read some papers by Google's people about some parts of their architectures (mainly the modified filesystem)

You don't really need thousands of dollars; if you have a fast-enough computer, you can use virtual machines to form a virtual network.

I doubt a new computer and new Virtualization software would cost thousands of dollars.

I assumed he was planning to set up something similar himself.

One good resource to study are the HOWTO documents.

Or for books, you can get books about "Clustering" and those related to Microsoft's MCSE (especially concerning Active Directory).
