If you work around Linux regularly, in some ways the latest amazing news is… not that amazing. The New York Stock Exchange, where the world’s largest public companies trade their stocks, is now running on Linux. (Microsoft is not listed on the NYSE; they trade on the NASDAQ. Now *that* would have been a fun headline…) In addition the Chicago Mercantile Exchange also runs on Linux. While perhaps not as famous as the NYSE, the CME is one of the largest exchanges in the world. Even the Tokyo Stock Exchange is running on Linux.
Why is this? Linux’s stability and flexibility make it an obvious choice for stock exchanges that mix in a wide range of server and real-time application technologies connected by global networks with extremely high security needs. People who work around Linux have always thought Linux really shines in these kinds of computing environments.
Still, the sheer amounts of money that are now traded on top of Linux are staggering. NYSE Euronext and its family of exchanges which include the NYSE, Euronext, Liffe, Alternext and NYSE Arca Options, operating in the US and Europe, now run on Red Hat Linux and look to Red Hat for support and services. Put it another way, over 4000 public companies and over $141 billion in daily stock transactions depend on Linux. The Chicago Mercantile exchange at last count traded 1.403 Billion contracts valued at $827 trillion annually. The Tokyo Stock Exchange has 2,413 listed companies have a total market capitalization of nearly 678 trillion yen.
Interested in hearing more from the kinds of developers and vendors that work on large, high-performance installations? The Linux Foundation is hosting our End User Collaboration Summit this fall in New York City, Oct 13-14. The leaders of the development and vendor communities will be interacting directly with CIOs and senior IT people to discuss in detail how to accelerate problem solving and advance the Linux platform. The author of Wikinomics will be there with his observations on collaborative development and I suspect to learn a little from the folks working on Linux. All verticals are welcome, including Online Services, Financial Services, Healthcare, and HPC.
It’s an invitation-only event, limited to 150 participants, so if you’re interested in attending, please don’t wait to get in touch. http://www.linux-foundation.org/events/enduser . If you have questions or need further information, please email us at email@example.com  .
