Last week IDC published its Worldwide Quarterly Server Virtualization Tracker for Q4 2009, reporting an increase in the amount of servers used for virtualization.
18.2% of all new servers shipped in the last quarter of last year in fact were virtualized, compared to 15.2% in the same period of 2008.
Despite that, the total amount of virtualized servers in 2009 was 5% less than in 2008, with a 14% decline in spending for virtualization hosts.
Virtualization software revenue didn’t go much better:
Worldwide virtualization software revenue for all CPU types declined 10% year over year in 4Q09 to $447 million, thanks primarily to economic pressures and an increasingly competitive marketplace. Virtualization licenses increased 13% year over year and 21% sequentially in the quarter but declined 7% for all of 2009.
