eBay Internals

http://www.addsimplicity.com/downloads/eBaySDForum2006-11-29.pdf - very interesting.
It is about some internals of eBay.
212,000,000 registered users, 2 Petabytes of data, 26 Billion SQL executions per day. But the most interesting for me is 3.3 million line C++ ISAPI dll - 150 MB. Oh man...

Notice on slide 15 it says that the C++/ISAPI was replaced with Java in 2002.

I'm not surprised that the scaling of the application tier is achieved via decoupling and asynchronous EDA.
