The techologist in me loves getting the monthly Web server report from Netcraft.com. Astounding statistics like the number of registered public Web sites (673 million in June, up from 23,000 in 1995) and active Web sites (188 million) put into the context of history shows simply and directly just how penetrating the Internet has become in our lives over the last 18 years.
But I've also been noticing the steady rise of a relatively new open source Web server called nginx (pronounced engine-x) (see the figure below, complements of Netcraft). Nginx is now the number two Web server of active Web sites at 24.3 million sites. For reference, the open source Apache Web server has 101.9 million active sites and Microsoft has 20.9 million. (The numbers always wiggle around a little month to month, so track the trend rather than the monthly changes.)
