Being a Linux enthusiast & hobbyist, I’m encouraged to see major industries make the decision to embrace Linux.
From the article:
The open-source operating system may not have all the polish of Unix technologies with 20-plus years of history behind them, “but it’s polished enough for us,” he said.
The NYSE’s shift toward Linux and x86-based hardware illustrates why analyst firm Gartner is predicting a slight decline in Unix server revenues over the next five years. In comparison, Gartner forecasts strong sales growth for both Windows and Linux servers.
Although Rubinow has the option of using HP-UX, HP’s version of Unix, he said that he’d prefer not to. “We don’t want to be closely aligned with proprietary Unix,” he said. “No offense to HP-UX, but we feel the same way about [IBM’s] AIX, and we feel the same way to some extent about Solaris.”
The NYSE still runs numerous Unix systems, especially ones with Solaris, which is Sun Microsystems’s Unix derivative. Rubinow acknowledged that Solaris has the ability to run on multiple hardware platforms, including x86-based systems from Sun server rivals such as HP. But he added that he thinks Linux “affords us a lot of flexibility.”
Also, having looked at Virtualization products like VMware, I found this paragraph very intriguing. I wonder why I haven’t heard of the latency-issue before with Virtualization, of course running an OS ontop of another would add latency, but the variants of Virtualization software that allow Virtual Machines to run directly off the server hardware without an OS host would (I would think) bring the latency to par with any OS, I suppose that thin layer separating the Virtual Machines running on the hardware do have some impact. From the article:
One technology that the NYSE isn’t adopting so eagerly is server virtualisation, which comes with a system latency price that Rubinow said he can’t afford to pay. In a system that is processing hundreds of thousands of transactions per second, virtualisation produces “a noticeable overhead” that can slow down throughput, according to Rubinow. “Virtualisation is not a free technology from a latency perspective, so we don’t use it in the core of what we do,” he said.
