Multiple servers working together for one website?

[Nick]

Just out of curiosity, I've been wondering how websites such as Facebook, Youtube, Google, etc. who have to have thousands upon thousands of servers get them to work together. How exactly is this accomplished?

An in depth explanation or link to where I could find one would be great.

Thanks

They use XSS.

If you are going to run a small site Failover technique will be ok, those big sites run multiple servers in many countries

Right... he's not talking about sites being taken down from multiple servers.

Nick, they are called Cluster servers.

Load Balancing & most likely "High-availability". I would assume Facebook would use their own soloution or something for this, since they're enormous. It's not cheap either.

It is simple if you think like this, your site is accessed in different countries

ex google.com
google.co.in
google.com.sg etc

you need to run multiple DNS servers, web servers to host the files for that particular region, separate data base servers and use hardware load balancers for balancing the traffic using different protocols.

Check in google with load balancers you can get the info on what a load balancer do to divert the traffic to different servers

A cluster alone is not the option, you would need something to distribute the requests to the different parts in the cluster.

Like Dynash said above it's basicly Load Balancing in combination with High Availability.

WHM has clustering as well but most providers don't allow it in the reseller interface.

Sounds like that to me as well. Peer1 offers load balancing and it appears YouTube is (or was) a customer of theirs. You can read what they have to offer: http://www.peer1.com/managed/load_balancing.php

That's not the same it's DNS clustering ...

Yep, they were. They used ServerBeach when they first started (Same company). Once they sold to Google though they pulled the site to Google's network.
