Top 10 Sites' Web Server Operating Systems

Out of curiosity, I decided to find out what the top web sites in the world were running on their servers-- Linux, Unix, Windows, etc.  Here are my results, retrieved Friday, April 2, 2010:

Ranking from http://www.alexa.com/topsites
Results from http://uptime.netcraft.com/up/
 

  1. Google ... Linux
  2. Facebook ... Linux
  3. Yahoo ... Linux
  4. Youtube ... Linux
  5. Live ... Win Server 2003
  6. Wikipedia .... Linux (Ubuntu)
  7. Blogger ... Linux
  8. Baidu (?) ... unknown OS, running Apache
  9. MSN ... Win Server 2003
  10. QQ (?) ... Linux

Baidu and QQ both appear to be Chinese or Korean web sites, I am not sure which.  As you can see, 7 out of the top 10 are running some flavor of Linux.  I think that speaks volumes about the reliability of the OS.

Linux reliability

I think you are right about the popularity of Linux's reliability, but I also think that the fact that the OS itself is free plays a big part in the business decision to use it instead of commerical enterprise operating systems.

I often wonder how many web startups and business ventures there would be if everyone had no choice but to pay a large single or recurring license fees just use or add to an OS platform, such as the Windows Server line.

How could you get it so

How could you get it so wrong. Google wouldn't dream of using windows regardless of price as would most other sites, it's an inferior operating system, both in performance and more importantly security. And it's IT experts who design the IT infrastructure. I'm sure a lot of guys at microsoft wish the could be running a linux box but cant.

confirmation

For your confirmation is google using chrome os or linux

Chrome OS is a desktop

Chrome OS is a desktop operating system. This article is about identifying which server OS is providing the platform for each web site.
