A recent “Top 1000 Application Servers Survey” of Fortune 1000 companies by Port80 Software shows that use of Microsoft’s ASP.NET, ASP, and Internet Information Server beat all of the competition combined.
The survey found that Microsoft platforms (ASP.NET, ASP) constituted
43.6% of servers, with Java platforms (J2EE, JSP, WebLogic, WebSphere,
Tomcat) coming in second place at 12.2%. The others are PHP at 5.2%,
ColdFusion with 2.7%, Perl at 2.3%, and Python (Zope) bringing up the
rear at a scant 0.1%.
As per this survey, with over 3 times more market share than Java, Microsoft seems well and truly in control of enterprise platforms.
