Linux is the only serious threat to Microsoft's increasing dominance of the market for server operating systems, according to new research from IDC.
Microsoft's share of new server operating environment license shipments grew from just under 42 percent in 2000 to nearly 49 percent in 2001, IDC of Framingham, Massachusetts, said in a summary of its recently released "Worldwide Client and Server Operating Environment Market Forecast and Analysis: 2002-2006."
On the client side, Microsoft's already overwhelming 92 percent share crept up to 93 percent in 2001. IDC analyst Al Gillen attributes the company's continued growth to its licensing programs and to customer transitions from older Microsoft products to its current software.
The overall operating-environments market expanded 0.7 percent from 2000 to 2001, according to IDC, with most of the growth coming from increased license revenue from client operating systems.
In the server OS market, Linux held the number-two position behind Microsoft in 2001, accounting for 25.7 percent of new license shipments, according to IDC. Novell Inc.'s NetWare captured 11.7 percent of the market, while Unix held a combined 11.6 percent and other products accounted for around 2 percent.
