I have to blog about the most interesting article I read about in a german IT magazine during my vacation last week.
The rough translation goes like this:
There was a conference in Germany that was about Open Source and TCO Die Pinguin Lösung. They had case studies comparing ... drumroll ... Linux and Windows (note, the news here is these are not predictions but case studies). One case study was about a big german media company. One system administrator was responsible for 60-80 Windows servers while people not less qualified administered only 25 Linux Servers on average.
More examination revealed that this was due to the fact that problem solving on Windows servers mostly consisted of a reboot while the Linux people did more thorough analysis.
Another case study showed that germans biggest Webhoster (hosting more than 3 mio domains) is hosting less than on percent of the domains on Windows servers but needs the same number of administrators for Windows as for Linux (one person administers 500 Linux servers). This is partly due to the fact that Linux is able to host on the same hardware 4-5 times as many domains as Windows. But more of a reason is that you can achieve a much higher degree of automation on Linux than on Windows (no suprise, but did you imagine that magnitude).
