And I thought I wasn't going to post anything today.
I just saw the article of ServerWatch on server sales on Q4'2008. I had been waiting for it for a while to see how bad the quarter had been given the economy.. but mostly I wanted to see how the GNU/Linux vs Windows battle on the server space is going.
For Q2 2008 (the IT sector not in decline yet): Windows had a YoY gain of revenue of 1.38% (with market share down to 36.5% from 38.2 one year earlier), UNIX gained 8.22% (market share up to 32.7% from 32.06%) and GNU/Linux had a revenue gain of 4.55% (market share down to 13.4% from 13.6%). GNU/Linux + UNIX make up 46.1% of revenue market share.
For Q3 2008: Windows had a loss of revenue of 2.86% (reaching 40.8% from 40.4%), UNIX lost -8.15% (ouch!.. down to 29.7% from 31.1%) and GNU/Linux barely made it even with a gain of 0.49% (reaching 14% from 13.4%) . GNU/Linux + UNIX held 43.7% of the market.
Q4 was a poem (if you ask me... I doubt Steve Ballmer will agree): Windows nosedived with a loss of 17.07% (double ouch!!... down to 35.3% of the market from 36.6%), GNU/Linux had a loss of 7.92% (reaching 13.6% from 12.7%) and UNIX lost 6.52% (reaching 36.2% from 33.3%). GNU/Linux + UNIX got 49.8% of the market.
The numbers and percentages can be a little misleading... so let me try to mislead you a little more: If you look at the amounts of gross losses/gains of revenue, for example, you will see that in Q2 2008, Windows had an increase of YoY revenue of roughly US$ 70 million, GNU/Linux made a little more with 80 million (it's hard to know cause the numbers are rounded, so perhaps the difference could have been a little less or more) but UNIX had an increase of 350 millions (wow!). Q3 is another story: Windows had a decrease of revenue of 150 million, GNU/Linux broke even and UNIX had a decrease of 330 million. And Q4... well, this is not for the faint of heart: Windows had a YoY decrease of revenue of..... 980 million, GNU/Linux had a decrease of 150 million and UNIX had a decrease of 340 million.
Bottom line: If on good times you are growing well, and on bad times you are shrinking less than your enemy... I think you aren't doing so bad after all, don't you think?
The second bottom line: These are statistics and we know that they can say whatever we want them to say.... so take those numbers with a grain of salt.
Disclaimer: The numbers, though I guess are right, could be wrong. I had to put together numbers from different sources (mostly IDC and Gartner) so that there could be a mistake here or there (though I wouldn't expect it to be so dramatic). Want to get the file I have with the numbers? Let me know and I'll email it to you.. perhaps we could improve it.
