"The Linux Foundation has released the results of a new survey of IT staffers at enterprises with more than 500 employees and more than $500 million in annual revenue. It found that large enterprises are increasing their investment in Linux for the third year in a row and that Linux is particularly important to companies that are adopting cloud computing or implementing big data projects.
"PCWorld's Katherine Noyesreported, "The past two years have already seen significant jumps in corporate Linux usage, but now it looks like that trend is continuing into a third year. To wit: While overall server revenue grew at just 3.1 percent and Windows server revenue increased just 3.2 percent in the fourth quarter of 2012 year-over-year, Linux experienced 12.7 percent year-over-year growth for the same period. Unix, meanwhile, was down 24.1 percent. That's according to the Linux Foundation, which on Wednesday released its 2013 Enterprise End User Report, focusing on Linux adoption." "
These results are open to the charge of bias, considering who conducted the survey, but interesting nevertheless.
No doubt. Keep in mind also that many enterprise IT staff are reluctant to admit the extent of Linux usage. They will naturally understate it. MS sales reps have very high company connections, lavish them with perks, and play harsh political games to keep their volume licensing clients in line.
