According to Port80 Software, which periodically surveys the public sites of Fortune 1000 companies to determine their use of web and application hosting technologies, Microsoft Internet Information Services 6.0 web server (IIS 6) gained 9.5 percent since August 2006, and passed IIS 5 to lead the survey for the first time, “outserving the open source Apache server and all other web servers among Fortune 1000 sites.”
Overall, IIS 4, 5, 6, and 7 deployments continue a four-year lead in the survey with a combined 55 percent share of all Fortune 1000 corporate sites, versus Apache’s 24.9 percent share.
Last week, a similar survey by UK-based research firm Netcraft found that IIS continued to narrow the gap with the open-source Apache web server, suggesting that Redmond’s offering could surpass Apache as early as next year.
It found that Microsoft grew to 36.2 percent of all active websites, while Apache lost nearly a million website names, as its share of active websites fell to 48.4 percent.
“While Netcraft’s recent surveys demonstrate the rise of Microsoft’s Internet Information Services across the Internet at large, Port80 Software continues to see IIS beating Apache among leading US enterprise companies,” said Joseph Lima, director of Product Development at Port80 Software.
“Having analysed Fortune 1000 websites for years now, we estimate that IIS 6 penetration will continue unabated while IIS 5/Windows 2000 servers are decommissioned, with a few Apache defections along the way,” Lima added.
“If the trend from previous surveys holds, IIS 7 should be the dominant web server for Fortune 1000 sites by 2011.”
