Spending by enterprises on servers is growing at an annual rate of just 3.1 percent. The three dominant enterprise server Operating Systems being used are Linux, Windows and UNIX. Not too surprisingly, enterprises are dropping older Unix servers in favor of Linux — Unix spending was down 24.1 percent in 2012, while Linux spending picked up some of the slack by growing 12.7 percent over that period. Windows server revenues grew at just 3.2 percent last year.
Over the next five years the shift towards Linux seems to be particularly clear, with 80 percent of large IT organizations planning to increase their purchases of Linux servers and only 20 percent planning to make additional Windows-server purchases.
These are the results of a global survey conducted by the The Linux Foundation of companies and organizations with sales of more than $500 million or with more than 500 employees.
Other findings from the Linux Foundation report include:
- 85.6 percent of respondents say Linux continues to improve
- 66 percent of respondents say that they continue to make new Linux server deployments
- 60.2 percent of respondents say that they are increasingly using Linux for mission-critical applications
- 95 percent of IT managers say that Linux has become more valuable to their missions than in previous years
- 70.3 percent say that they prefer to use Linux for their cloud computing needs
- 60 percent of CIOs say that Linux is strategic for their organization
- 38.3 percent say that a major concern about Linux is the lack of skilled Linux IT professionals
- Cost no longer is the top reason cited to be using Linux. Instead, technical superiority and security are considered to be the main benefits.
Amanda McPherson, vice president of marketing and developer services of the Linux Foundation, said that “We see the growing success of Linux adoption in the enterprise, especially as it’s used for the most important areas of business, leading to the rise of Linux and collaborative development across many industries. Having a realistic understanding of where Linux is gaining traction in the enterprise helps to inform vendors and users about how they can work together to advance Linux and the technologies it supports.”
