Years ago Sabre Holdings, a big player in the travel business, used UNIX operating systems on SPARC servers. A few years ago they started phasing out older UNIX servers for GNU/Linux on Intel for huge savings and better performance:
“The move to Linux and Intel has saved Sabre substantial amounts of money, Wiseman says, but it was only possible because he was convinced that it would prove reliable enough to replace the NonStop and Solaris systems. As things turned out, Red Hat’s Linux has proved rock solid, vindicating his position. “In fact we haven’t had a single outage because of Linux,” says Wiseman. “The only outages we have had are from hardware failures, but because the hardware is so cheap we can have redundancy to overcome that, he says.””
Sabre did look at that other OS but decided they did not want the lock-in. Having decided to move to Intel processors, they did not want to have to change software again if they moved to another CPU and GNU/Linux runs on everything…
Recently HP has been their “goto” organization to manage their empire of IT and HP has committed to supporting RedHat on their servers for “mission-critical” applications as more of their customers move to GNU/Linux. Sabre has made a deal for support from HP for six years and $800 million.
Sabre has a lot of good things to say about RedHat GNU/Linux for their global network with 24×7 uptime, three times faster and 90% cheaper than UNIX on SPARC on thousands of servers:
While the use of FLOSS and GNU/Linux on servers for big businesses is easy to understand on price/performance, the same advantages come to businesses who use GNU/Linux on the desktop. I recommend Debian GNU/Linux because it works for me and schools where I have worked but RedHat seems to be the preference of many businesses because of the support and business-oriented attitude of RedHat.
