"The Johannesburg Stock Exchange (JSE) has announced that it is
moving to an all Linux based trading platform when it relocates to
Johannesburg. The JSE currently operates out of London and runs on
the TradElect platform which is based on Microsoft .Net and SQL
Server 2000. It plans to move to MilleniumIT's Millennium Exchange
platform by the first half of 2012.
"The JSE is following the example set by the London Stock
Exchange. That exchange also ran the TradElect platform, but in
2009 began the process of migrating to the Millenium Exchange
system using Linux and Solaris based systems. The LSE also
purchased the Sri Lanka based developers of Millennium Exchange,
MillenniumIT, for $30 million."
