Red Hat executives say they are going after Windows workloads in the enterprise and winning their share of deals. However, the effort will take time and the battle is really over new computing workloads.
The Red Hat Enterprise Linux-Windows Server duel is worth noting. According to IDC's most recent data, Windows servers have 47.7 percent of the market with third quarter revenue of US$5.6 billion, up 26 percent from a year ago. Linux servers represent 17.5 percent of industry revenue and third quarter revenue grew 32.6 percent to US$2.1 billion. Unix server revenue has 21.5 percent market share, but is fading. IBM's z/OS has 8.6 percent of the server market.
In a nutshell, Windows servers have the most market share and nice growth. It's just a matter of time before Linux servers eclipse Unix to become No. 2.
