This ought to please the ad wizards in Redmond-based Microsoft Corp. (NASDAQ: MSFT). In two separate surveys recently, the results showed that Microsoft's Internet Information Server (IIS) product was growing faster than one of the world's most popular web server software systems -- the open source Apache Server that runs on the free Linux operating system. Maybe we'll see Microsoft CEO Steve Ballmer do another monkey dance soon.

Is this a celebration moment for Microsoftites? Possibly. NetCraft found that Microsoft's IIS was steadily gaining in popularity as a web-serving platform across the globe, and Port80 found that IIS was beating the free Apache web serving platform among enterprise systems in corporate America. Microsoft's web-serving systems have been around for quite some time, but have never been as popular as some of the competition (and Apache doesn't even cost anything).

Is Microsoft finally becoming a threat to open-source software at the computer server level? These surveys would seem to indicate that, although a few surveys in one year doesn't make an airtight case at all. There are also many things about the DIY nature of open-source computer systems that make survey results difficult to tabulate into meaningful data. Still, survey facts don't lie: Microsoft's IIS saw usage on 36.2% of all active web sites at the same time that Apache lost nearly a million web site names (dropping to a 48.4% market share).
