When it comes to the fast-moving business of trading stocks, bonds and derivatives, the world's financial exchanges are finding an ally in Linux, at least according to one Linux kernel developer working in that industry.
As an alternative to traditional Unix, Linux has become a dominant player in finance, thanks to the operating-system kernel's ability to pass messages very quickly, Lameter said in an interview with IDG. In fact, the emerging field of high-frequency trading (HFT) would not be possible without the open-source operating system, he argued. Lameter himself was hired as a consultant by one exchange -- he won't say which one -- based on his work in assembling large-scale Linux clusters.
An interesting read regarding the use of Linux in high-frequency trading applications.
