The Linux Foundation today is releasing its annual Enterprise End User Report.  Because this is the third year we've surveyed the world's largest enterprises and The Linux Foundation's End User Council about Linux adoption, we're able to share some interesting trending data.
But perhaps most interesting is the opportunity to understand how Linux is outpacing Windows in server revenue in the enterprise. IDC's latest quarterly tracker  shows Linux growing at 12.7 percent year-over-year while Windows is stagnating at 3.2 percent year-over-year growth. In fact, the quarter prior (Q312) , Windows was actually in decline while Linux was growing.
This momentum is mirrored in our report: More than 80 percent of respondents plan to increase the number of Linux servers in their organizations over the next five years, compared with just 20 percent for Windows.
What these numbers don't tell us, though, is why this tipping point is happening now. Our Enterprise End User Report sheds some light on this question. Some key highlights from today's report include:
* Linux powers the cloud. For enterprises using cloud computing, Linux is by far the dominant platform with nearly 76 percent of cloud-enabled organizations using Linux servers for the cloud, and 74 percent planning to maintain or increase their use of Linux for future cloud initiatives.
* Almost no one is building anything new with UNIX or Windows. More than 75 percent of enterprises reported deploying Linux for new applications, services and greenfield deployments in the last two years, a number that has grown nearly 10 points since our first survey.
* Dramatic increase in Linux use for mission-critical workloads. The number of organizations with plans to increase the use of Linux for mission- critical workloads has grown consistently year-over-year to reach 73 percent in 2013 (a 12.8 point increase over our first survey).
We invite you to read through all the results in the complete report  and share it with your colleagues. The information will help inform conversations that will take place at the upcoming Enterprise End User Summit  in New York at the NYSE May 14-15, 2013.
Based on the data in this report and numbers being reported by IDC and others, we expect the usage of Linux to continue to rise, especially as cloud computing grows. These are good times for Linux.
