How Facebook Runs Its LAMP Stack

prostoalex writes "At QCon San Francisco, Aditya Agarwal of Facebook described how his employer runs its software stack (video and slides). Facebook runs a typical LAMP setup where P stands for PHP with certain customizations, and back-end services that are written in C++ and Java. Facebook has released some of the infrastructure components into the open source community, including the Thrift RPC framework and Scribe distributed logging server."

That has little to do with the infrastructure and more to do with the site design. Please don't blame the sys engineers/admins for the poor interface design.

Well, the fact that they gave a talk about their LAMP stack tells you that they consider engineering more important than site design. Furthermore, a poor choice of infrastructure makes doing good site design hard.

And that's my point: Facebook is evidently driven by system stuff and programmers, while it should be driven by site design.

Clearly, $MY_SPECIALTY should drive the entire system! They made a big mistake by allowing $OTHER_SPECIALTY to take precedence. Everyone knows that only $MY_SPECIALTY should dominate all design plans. Duh.

If your site infrastructure is influencing how you design, you've made some sort of monolithic error along the way. Good code completely separates the content from the design. It's not like they've just hacked up a Wordpress install (which seems to go out of its way to tie content and design together) - Facebook employs hundreds if not now thousands of programmers; it's pretty safe to assume there's at least one UI/UX specialist on board as well.

All things considered, I'd actually say that Facebook's design is pretty decent, but that's of course a matter of opinion. A lot of the code that went into that design sucks, but that's what happens when you have to support IE6. Regardless, I think it's great that they're sharing knowledge about how they've managed to use and customize an infrastructure to support 200,000,000 users, especially with the amount of traffic they have to deal with. That's well beyond the scale that many governments have to worry about!
