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.
