GNU/Linux a King of Servers, But Microsoft Boosters Disagree

Linux Market Share



Summary: Using flawed and partly Microsoft-funded numbers, the advocates of proprietary software beg to suggest that GNU/Linux is declining (which it's not)

SEVERAL days ago, Pingdom published this reminder which shows how GNU/Linux dominates the top end of computing.

Most popular supercomputer OS

Here below you can see the division by operating system family across the top 500 supercomputers.

1. Linux (89.2%) 2. Unix (5.0%) 3. Mixed (4.6%) 4. Windows (1.0%) 5. BSD based (0.2%)


Two days ago we wrote about Gartner's bogus numbers referring to server 'share' (improperly measuring the wrong things). One thing we did not highlight at the time (or in more detailed posts on the subject) is that a supercomputer/mainframe would count as one server and so will a dual-core machine. Since GNU/Linux is dominant at the high end, any number of units (let alone just sales of boxes, as opposed to installations) is going to demote Free software, by the very definitions chosen.

Microsoft booster Preston Gralla* takes IDC/Gartner numbers (they deceive in the same way) and he is being very dumb, as usual. SJVN sets him straight.

But Gralla and other critics are missing that IDC is not measuring what server operating systems are being used; it's measuring what server operating systems people are buying, and those are bundled with their hardware purchases. Specifically, to quote IDC, the researchers are measuring "server revenue includes components that are typically sold today as a server bundle, including frame or cabinet and all cables, processors, memory, communication boards, and OS."


Another piece of disinformation that's floating at the moment cites the Microsoft-sponsored Net Applications. Adversaries of Free software are desperate for something to boost their own ego as Microsoft's results are still declining [1, 2, 3, 4] and their expenditures rise. ⬆ ______ * For the uninitiated, see [1, 2].

"It means a situation in which somebody accuses someone else of a fault which the accuser shares, and therefore is an example of psychological projection, or hypocrisy. Use of the expression to discredit or deflect a claim of wrongdoing by attacking the originator of the claim for their own similar behaviour (rather than acknowledging the guilt of both) is the tu quoque logical fallacy."
