Dortmund’s Servers

“The city of Dortmund, Germany’s 8th largest city, is rapidly increasing its use of Linux. From 2015 to 2016, the number of Linux servers rose by 21%, from 200 to 242.”

This is interesting to me: While Dortmund uses more TOOS servers than GNU/Linux servers, they have three times as many physical GNU/Linux servers as TOOS servers… This could support the thesis that GNU/Linux servers can handle more load than TOOS (Conversely, it could suggest the opposite…). Anyway, this news doesn’t tell us much about what these servers are doing. There must be a reason for using 61% of instances TOOS, or perhaps that’s just a phase they are going through and they are shifting loads from one OS to another. Nevertheless they keep increasing numbers of TOOS instances, albeit at a lower rate than GNU/Linux. I guess you’d have to be there to know and the guys who are aren’t talking…

    OMG! More pie for us all! Grece for POTUS!

    Given that there are two options, namely “Windows” and “Linux”, if the share of one goes up, the share of the other must go down. Or are you too stupid to understand the concept?

    Grece if you have last year numbers the Windows Physical went down there is particular data that is not allowed on cloud services by German law over governments..

    I am almost certain that the city decided to roll with Linux on Azure, which is just Linux under an existing Windows server.
    The year before number has most of the Linux growth as Physical. Yes more Physical Linux servers were added than the total number of Windows Physical Servers they have.

    Grece don’t wild guess the government documentation it out there if you know where to look.

    What would be interesting, is to find out which are actual servers versus virtual servers. I am almost certain that the city decided to roll with Linux on Azure, which is just Linux under an existing Windows server.

  5. Grece wrote, “Microsoft usage went up as well in parallel.”

    Share of servers went down.

  6. Grece says:

    If you look at the chart, Microsoft usage went up as well in parallel. Now, I would understand if the Microsoft values declined, but they did not. This story is a failure.

    There is interesting data in the graphic.

    3 % Windows physical so running on bare metal and 23% Linux physical running on the bare-metal. So this kinda paints a interesting question.

    How are they counting servers? Physical or Just instances. If the total physical numbers are 3%(20 Windows servers) vs 23%(156 Linux) then most of the processing has to be happening on Linux. Yet Linux solution is not using as many virtual instances and that would kind of make sense with Linux supporting Containers.
