This article is misleading. Linux is not the most popular operating system. Linux is the most popular development platform. This is not a surprise. I’ve been working in IT for 20+ years, and I’ve never seen node.js or JBoss running in Windows. Windows Server, for development, is dedicated to .NET. There’s too much fumbling with IIS necessary to not only get Javascript running stable but SECURE. Linux is a better option.
In my 20 years, aside from the early years with Novell Netware, I’ve not worked in an environment where Windows Server wasn’t the preferred infrastructure back end. Active Directory is hands down the best LDAP solution out there.
I wonder how much of its popularity is tied to the fact that it is free.
This article is not misleading. From the title on down, it is talking only about development platforms. There is no mention anywhere in this article about general, end-user, usage.
