LINUX IS WINNING cloud market share in the enterprise, according to the Enterprise End User Trends Report 2014 just released by the Linux Foundation.
The report was based on a survey of 774 members of the Linux Foundation's End User Council and others by the Linux Foundation along with Yeoman Technology Group, with more than 75 percent of the large enterprises surveyed using Linux as their primary cloud platform, fewer than 24 percent of organisations primarily using Windows and less than two percent primarily using proprietary Unix.
The most striking finding was that cloud deployments on Linux are increasing at the expense of Windows. In 2011 the survey found that 65 percent of cloud deployments were on Linux and 45 percent were on Windows, while this year Linux was used for 79 percent of cloud deployments and Windows was used by 36 percent.
In other words, new cloud implementations on Linux increased by 14 percent over the past three years, and Windows cloud implementations declined by nine percent.
It also seems apparent that the percentage of enterprises in transition from Windows to Linux, or at least hedging their bets by deploying both, has increased from 10 percent to 15 percent over the same period, with the momentum of relative market shares clearly having shifted in favour of Linux.
The survey found that 87 percent of enterprises are adding more Linux servers this year, and 82 percent plan to add more Linux servers next year.
Another salient finding was that enterprises rated operating system features as their principal reason for using Linux as their primary cloud platform over Windows, with higher security and lower total cost of ownership tied for second.
The survey found that 78 percent of enterprises regard Linux as more secure than most other operating systems. This isn't surprising, since 75 percent use Linux as their primary cloud platform and 79 percent of deployments use Linux.
Only 17 percent of respondents rated other operating systems' security as 'about the same' as Linux.
A third insight of the report is that, while Linux virtualisation continues to dominate cloud deployments, with 67 percent of enterprises using Xen or KVM, 16 percent already have Linux containers deployed, and they are under evaluation or planned by 49 percent.
