In a series of reports over the next six weeks, IDC will declare that Linux is well-positioned to continue gaining ground in businesses at the expense of other operating systems. The company predicts spending on Linux hardware, software, services and staffing will grow to 9 percent of corporate IT budgets in 2002, up from 3 percent in 1999.
"The willingness of an increasing number of decision-makers to look closely at Linux bodes well for its future and suggests increasing challenges for competitive platforms," Scott McLarnon, study director and group vice president at IDC, said in a statement.
Linux is seen as an alternative to proprietary operating systems and has several advantages to offer for businesses: it is open-source, meaning that companies can tweak the code themselves, and it is inexpensive, since there are no license fees.
The studies found that 40 percent of the 800 decision makers surveyed in North America and Western Europe are actively using or piloting Linux, and that Linux unit replenishment rates were twice as high as those for Unix.
But increased availability of Linux software and support is crucial, McLarnon said. Traditionally, one of the factors giving established operating systems such as Unix an advantage over Linux has been the availability of a wide range of tried-and-tested applications.
IDC's figures are likely to be controversial, as are many studies involving Linux. In June, for example, Gartner and IDC reported vastly different conclusions on Linux's penetration into the server market. Gartner found that Linux accounted for just 8.6 percent of US server shipments for the third quarter of last year, while IDC insisted that Linux accounted for nearly one-third of the total server market.
At that time, Microsoft, one of the sponsors of the Gartner study, said the figures proved that Linux is ultimately a "niche play."
"While many users have bought Linux to try it out, a large number of those copies bought, downloaded and acquired were tested and then never actually used," said Doug Miller, Microsoft's director of competitive strategy for the Windows division.
However, other factors are in Linux's favor. Large companies like IBM and Compaq have signed up to promote the operating system, with IBM promising to spend US$1 billion on Linux projects this year. IBM recently stepped up its Linux push to include its iSeries line of servers.
A Microsoft spokeswoman said it was difficult to comment on the report since the company has not seen it yet. However, she said, "We believe it is important to have a healthy software industry where open source software and commercial software co-exist".

Lower admin costs, lower insurance premiums, greater reliability and can be adapted to changing requirements.
That makes it hard to decide for a competing system which needs to be rebooted regularly just to keep it running.
