Based on a survey of 1,000 information technology administrators and corporate executives at companies around the globe, Yankee's report concluded that the technical merits promised by Linux and applications built tohave yet to overcome financial concerns related to adopting the software. At companies with 5,000 or fewer users, Linux can than other systems, including Unix and Microsoft's Windows software, said the Boston-based company.
"Clearly, many people who have Linux like it a lot, but if you propose a wholesale swap to most large companies, you're looking at a significant up-front cost, and many executives are asking why they should do it," said Yankee analyst Laura DiDio, who authored the report.
Much of the expense of themigration comes from shifting the IT architecture, DiDio said. However, many executives are reconsidering such a move because of a growing number of and a dearth of experienced Linux administrators. Improved security has been one of the primary advantages Linux promises.
Another concern among users is the relatively small number of applications, compared with Unix or Windows.
"Everyone has a Linux strategy, even if it's just to throw rocks at Microsoft," DiDio said. "But executives are asking if the advantages of Linux are substantial enough to justify the expense and inherent headaches of swapping all of their systems."
In response to the survey, Linux vendors said their customers often garner sizable savings from moving to their software. Leigh Day, a spokesman for, the top seller of the Linux operating system, said their customers who switched say they have opportunities to spend less. Customers can also shift to cheaper hardware, specifically lower-cost , she said.
According to DiDio, however, Microsoft has made inroads with many customers who were considering Linux. For example, the company has been improving its ability to protect againstand has reworded its product warranties to convince end users that it is willing to take on greater levels of liability than its .
Although Linux advocates will argue thatwill provide long-term savings, the analyst said executives remain unconvinced that the Linux market is currently mature enough to serve their needs.
"A lot of end users feel it's perhaps still better to deal with the devil you know than deal with the devil you don't know," she said. "They feel that it's great that Linux is out there as an alternative--in particular to Microsoft--but market maturity and the number of available applications are major concerns."
Yankee said it conducted the survey with Sunbelt Software and that the research was not sponsored by any outside company.
