Open-source for business
Despite the legal uncertainties affecting Linux, open-source software development and use is growing in the enterprise community, even in mission-critical environments and business sectors.
One of the more unlikely developments in the software industry during the last few years has been the rapid uptake of Linux in the financial services sector.
Most of the Linux deployments in this sector have been for non-trivial data-intensive applications on blade servers, and are at the core of investment bank operations.
We shouldn't be surprised. Several leading players, most notably Intel, HP, IBM and Oracle, have been pushing Linux as a cheaper, more flexible alternative to Unix. The ISVs have followed suit. The financial services sector depends on compute power, and Linux on blade servers is both cheaper and more scalable than the alternatives.
The main driver for Linux adoption has been price/performance. Lehman Brothers moved to Linux after losing a thousand servers in the attack on the World Trade Centre, claiming "a 50 per cent improvement in cost and about a 20 per cent improvement in performance", and Morgan Stanley claimed to have achieved a 13-fold increase in performance after switching its equity options calculator from Solaris to Linux in November 2001.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
