Port 80 Software (www.port80software.com), developer of Microsoft web server add-on tools, has conducted a web server survey in June that has shown that half of top 1000 corporate websites run on Microsoft IIS. Survey results show that 53.9 percent of the sites use Microsoft IIS, while 20.3 percent use Apache and 14.6 percent Netscape. The remaining 11.2 percent use other platforms such as Sun One, Lotus Domino, Weblogic, Websphere, IBM and Zeus.
According to Port 80, the overall market share of main web server platforms has shown only a slight change during the year to date. Apache has gained 4 percent market share, but Port 80 attributed part of this gain to a small change in its methodology. Microsoft IIS 6 has demonstrated the highest growth of any single platform version from 0.5 to 5.5 percent in just one year.
Port 80 uses the websites of the Fortune 1000 companies, because according to the company, this data sample is more significant for business decision makers. Netcraft (www.netcraft.com) conducts a different web server survey that calculates web server software usage on all Internet connected computers. Netcrafta€™s latest survey indicates that Apache is used on 67.35 percent of the servers and Microsofta€™s market share is 21.32 percent.
