We discuss the statistics of foreign IaaS providers, give figures for our cloud and talk about the reasons that influenced such a spread of open source OS.

Distribution of shares
On IDC, in 2017, 68% of in-house and cloud corporate servers were running Linux. Since then, this figure has increased - this trend can be traced by many IaaS providers.
In 2015, representatives of Microsoft that every fourth instance in the Azure cloud runs on Linux. Two years later, their number 40%. This year the number of Linux machines . The IT company itself has also become a heavy user of the open operating system. For example, software-defined networks (SDN) of an organization are built on its basis.
A similar picture is observed in the clouds of other IaaS providers. For example, in the 1cloud.ru cloud, 44% of virtual machines run under Linux. In the case of Windows, this figure is 45%.
Shares of operating systems on active servers in the 1cloud cloud
“We expect that in the near future Linux can become a leader and bypass other operating systems,” comments Sergey Belkin, head of the project development department. . Considering that only a few years ago virtual machines deployed in our cloud were running on Windows.”
The forecast is confirmed by the statistics of other IaaS providers. For example, in a private cloud of one of the largest Western vendors, Linux runs .
However, the open source operating system remains the most popular web hosting platform. By analytical agency W3Techs, 70% of the ten million most popular sites are deployed on Linux servers (according to ). The remaining 30% is owned by Windows.
Why Linux
Experts identify at least two factors that affect the distribution of the operating system in the cloud.
Architecture flexibility. This factor in the Linux Foundation one of the defining ones. Linux is suitable for multi-tasking and runs on platforms of all sizes, from mobile devices to supercomputers. For example, in 2017, 498 supercomputers from the top 500 list running this open source operating system. But by the end of the same year, 100% of computers in the top began to work on Linux.
The world's most powerful supercomputer, IBM's Summit . The first US exascale supercomputer, scheduled to be completed in 2021, will also work .
Extensive community. The Linux codebase is being updated approximately . Since 2005 15 thousand engineers contributed to the development of the core. Among them are employees of 200 large corporations. Only in 2017, 3% of changes in the codebase developers from Google and Samsung. For 13% of changes "responsible" in Intel.

Large IT companies are actively involved in the development of both Linux itself and open source products based on it. Microsoft offers a platform for IoT applications, which is based on the Linux kernel. Intel launched a cloud project , in which engineers optimize the open source OS to run on their processors. HPE offers for delivery with their equipment. IBM acquired RedHat and is now developing one of the most popular distributions on the market.
New open source products are being actively implemented in cloud environments, which has a positive effect on the distribution of Linux.
What's next
The exact figures on the popularity of a particular operating system in the cloud environment should be treated with a certain amount of skepticism. The modern IT infrastructure of cloud providers is complex. Many hypervisors can be called "nested", and there are situations when one operating system runs in the environment of another.
But even with this fact, it's safe to say that Linux is increasingly being used in the cloud.
