Call out the chaperons — they’re practically touching! Apache and Microsoft IIS market share! They’ve almost met in the middle at 50%! Six inch space and no kissing, please!
Well, close, but not quite. Apache continued its “winning streak” in September over Microsoft’s Internet Information Server, but by a smaller margin than the month before (when Netcraft, which watches these kinds of things like a hawk, said that IIS was poised to challenge Apache’s market share lead sometime soon).
Part of this — as we’ve reported before — is due to Tomcat and to Google’s big server switch in 2006. Both of these phenomenons had a profound affect on Apache’s numbers, but were not in and of themselves an indicator of any slippage.
However, all that said, IIS is growing thanks to a rise in social networking sites like MySpace and Windows Live Spaces, both of which use ISS.
The high growth so far this year has been largely driven by the increasing number of online blogging and social networking communities. This month sees strong growth in the number of sites at Windows Live Spaces, MySpace, and Blogger appearing in the survey. The increased popularity of these blog hosting services continues to have a dramatic effect on the web server market shares: Apache suffered a sudden decline in share when sites at Blogger switched to Google’s GFE.
Apache gains over 3 million hostnames, and around 0.9 million active sites this month. But this is not enough to prevent its market share declining closer to the 50% mark, as Microsoft also gained over 3 million hostnames (a large part of which come from MySpace and Live Spaces, both of which use its Internet Information Server).
So the battle continues.
