“Forty percent of servers run Windows, 60 percent run Linux…”
–Steve Ballmer, Microsoft CEO (September 2008)
CONTRARY to figures that account only for shipped volume and revenue (IDC), the installed base of GNU/Linux servers is very high. This is not to be confused with “market share”, whose definition gets changed so as to serve the vanity of companies which directly or indirectly fund such market surveys. There is a lot of selective research and cherry-picking of methodologies.
GNU/Linux is very commonplace on servers. Virtualisation requires those servers to communicate between and within one another, either through open standards or ‘interoperability’, which is typically a two-way bridge. Microsoft is fiddling with companies like XenSource (now absorbed by Citrix) and VMware (now run by former Softies) to interfere.
In order to understand how GNU/Linux is doing against Windows on the server, a market survey would be required which is global. It is harder and more expensive to conduct a survey based on actual deployments (global in particular), as opposed to assembling and aggregating numbers of shipments from market leaders.
“In order to understand how GNU/Linux is doing against Windows on the server, a market survey would be required which is global.”One indicator of the success of Linux on the server is internal intelligence conducted and/or used by Microsoft. The company calls this — albeit just internally — “Linux heat map” (we have a copy of a court exhibit from Comes vs Microsoft
[PDF]). Publicly, realisation of the GNU/Linux threat to Microsoft can be arrived at by interpreting the company’s rhetoric and actions, such as threats of litigation, secret deals with Fortune 500 companies that pay Microsoft for their use of GNU/Linux (this is scarcely reported in the press and the companies refuse to identify themselves), and also disinformation initiatives such as “Get the Facts” and “Linux Personas” (defunct just days after debut).
Internal documents which were revealed in the Comes vs Microsoft case not only reveal figures about market share in several areas. They also show the company’s executives running frantic about what they called "Linux infestation". They said they were not on a path to win against "Linux", so they tried to manipulate Dell into dropping or neglecting GNU/Linux (on servers) and they also decided to commission studies which show GNU/Linux to be more expensive [1, 2]. Failing the first time, Microsoft argued, they can simply try again. This methodology fits well with tactics that are presented in internal Microsoft talks about "Effective Evangelism". One of the tactics is to manufacture evidence that you need and then reference it. Analysts can be compensated in many ways that escape the public eye, as detailed in the company’s presentations (all endorsed by Bill Gates by the way).
In one of the documents disclosed in Comes vs Microsoft, Microsoft was seen explicitly asking IDC to remove signs of its sponsorship of a study. This study accidentally showed GNU/Linux (server) to be superior. Microsoft had similar studies conducted with market research groups like Yankee and Gartner.
It is worth emphasising that what challenges Microsoft is not just the market share of GNU/Linux. It’s more complicated than that. As netbooks (sub-notebooks) have demonstrated, tough competition from Linux not necessarily leads to erosion of Windows’ market share; instead, it rapidly leads to erosion of margins. Sources suggest that Windows has become virtually free (gratis) for some form factors, whereas in the case of servers, Microsoft has promotional means for advancing Windows not only through advertising campaigns. I have heard personally from Web hosts who were offered Windows for free so that they migrate away from GNU/Linux. In one case, the source was offered subsidies of hardware as well.
All in all, this comes to show that it’s a multi-faceted issue which can be addressed and treated by considering questions like:
- How has GNU/Linux affected Microsoft’s/Windows market share?
- How is market share defined?
- How has GNU/Linux affected Windows margins?
- What is the difference between perceptual GNU/Linux quality/market share compared to reality? There is room for distortion here and it is actively being exploited, as shown by authentic court evidence.
- How failure-proof is GNU/Linux? How many companies are involved in developing and supporting it? Symbian and Palm OS, for example, have a single breaking point.
