Architectures of massive Websites

After my little Rant the other day, lets talk about something really cool. Having worked on a few load tests projects (mostly "enterprise" software like CRM and ERP), i find it quite remarkable how sites like Flickr, YouTube, Digg or LiveJournal can handle (extremely) high traffic with lots of inexpensive hardware and mostly open source software. The enterprise products on the other hand are often far away from beeing allowed to be mentioned along the word 'performance' in the same sentence ;-) (but heh, that's not too bad since it does mean more work for us load test guys :-))

I found this nice Google Techtalk about the YouTube architecture, which is really worth watching.

Another nice source for informations on the architectures of those high traffic web2.0 sites is High Scalability

Update: oh, did i mention that YouTube build their appserver in the beautiful Python language... ;-)
