If you have a site as massive as Wikipedia, hit as many times a day by as many people as it, what are you going to do? We're talking more than 10 million distinct articles, in 250 different languages, served to over 684 million people per year.
The answer is that Wikipedia have a massive server farm driving their web site – some 400 servers, in fact. And each and every one runs Linux. Now, here's something I really want to hit on: how many systems administrators does it take to manage 400 Linux servers? Let me tell you! Five. That's right, it takes just five full time IT staff to run each and every one of Wikipedia's 400 Linux servers. Actually, I exaggerate. These five people are Wikipedia's IT team in general; they have other duties to perform besides running the servers. So, we're talking about a massive web site that demands high availability and it is handled at a ratio of 80 servers per person. Now, I don't want to be presumptuous, but do you believe one single Windows administrator can maintain 80 servers by him or herself? What do you think the effort involved in distributing patches would be? Or, perhaps I should ask what would be the cost, if you chose to implement Microsoft Systems Centre or Symantec Altiris or other such big hitters?
