“Today’s news that TSE (Tokyo Stock Exchange) has moved
to Red Hat’s RHEL (Red Hat Enterprise Linux) as the operating
platform for its next-generation “Arrowhead” trading system
shouldn’t come as a surprise. Linux has become the smart stock
market’s operating system of choice.“Red Hat has been working with TSE and Fujitsu for some time on
the Arrowhead platform. As always with stock markets, the name of
the game is to accelerate TSE’s order response and information
distribution speeds. According to Red Hat, “Arrowhead is designed
to combine low latency with high reliability to accommodate diverse
products, trading rules and changes within a short time
window.””
