#2They have a lot of RAM. Dang.

#4> Twitter knows a lot about you from who you follow and what links you click on.
No kidding. But we don't care as we live in the glass house of a celebrity culture.
PS: downvote the quoted text if you must. My point is not obvious.

Not as much as I would have thought.
2TB can be one server: http://www.supermicro.co.uk/products/system/5U/5086/SYS-5086...
An expensive server for sure... but it's just one server.

If you expect others to misunderstand you, perhaps try to better represent your thoughts?

#7Here is a similar talk that Jeremy Cloud gave at QCon NY a few weeks ago: http://www.infoq.com/presentations/twitter-soa
Jeremy Cloud discusses SOA at Twitter, approaches taken for maintaining high levels of concurrency, and briefly touches on some functional design patterns used to manage code complexity.

I would absolutely trust someone named Jeremy Cloud on this subject.

Thank you for sharing it.... I was wondering about the video.

#10I really question the current trend of creating big, complex, fragile architectures to "be able to scale". These numbers are a great example of why, the entire thing could run on a single server, in a very straight forward setup. When you are creating a cluster for scalability, and it has less CPU, RAM and IO than a single server, what are you gaining? They are only doing 6k writes a second for crying out loud.
