Linux, Unix more reliable than Windows

Year spent going backwards

LAST YEAR, WE wrote about a controversial report penned by technology research and consulting outfit the Yankee Group, claiming that Windows was more reliable than Linux.

The Yankee Group has been busy again this year, but its latest report seems to offer a very different story to last year’s, with Windows now performing significantly worse than its Linux and Unix rivals.

The Yankee Group's second annual Server Operating System Reliability survey takes pains to note that all the major operating systems are in fact fairly reliable when it comes down to it, but that some have come on leaps and bounds, while others have slipped since last surveyed.

Like last year, UNIX, the main Linux distributions from Novell and Red Hat as well as open sauce Ubuntu, was again found to be heads and shoulders above the rest, with 99.999% reliability, taking the title of undisputed victor in Yankee’s 2007-2008 Global Server Operating Reliability Survey.

The study points out that IBM's AIX UNIX came out on top reliability wise, with only about 30 minutes of annual downtime per server. HP and Sun Microsystems also came out shining.

Managing to take the medal for “best improvement in reliability” was Red Hat Enterprise Linux (RHEL) and Novell SuSE Linux, who were each able to cut per annum downtime per server by about 75 per cent.

Window was slammed by the survey, however, for increases in downtime of approximately 25 per cent, totaling about nine hours of per annum downtime per server -significantly more than last year.

Explanations for Windows’ fall from Yankee grace seem to centre on the fact that the Vole put out a number of security alerts last summer and autumn, which meant that network administrators took their Windows Server 2003 machines offline for notably longer in order to apply remedial patches to them.

So, in a turning of tables, Windows 2003 Server is now considered a less reliable server operating system than Linux.

The Yankee Group claims to poll about 700 users hailing from 27 different countries. Preliminary findings from the report are published by the Institute for advanced Professional Studoes, here. µ
