Study: Linux is still the most popular OS in the cloud
We discuss the statistics of foreign IaaS-providers, give figures on our cloud and talk about the reasons that influenced this distribution of open source operating systems.

According to IDC, in 2017, 68% of in-house and cloud corporate servers were running Linux. Since then, this figure has increased - this trend is traced by many IaaS-providers.

In 2015, Microsoft representatives said that every fourth instance in the Azure cloud works under Linux. Two years later, their number was 40%. This year, the number of Linux machines exceeded 50% . The IT company itself has also become an active user of an open operating system. For example, on its basis, software-defined networks (SDN) organizations are built.
A similar picture is observed in the clouds of other IaaS-providers. For example, in the cloud 1cloud.ru under Linux, 44% of virtual machines are running. In the case of Windows, this figure is 45%.

The forecast is confirmed by the statistics of other IaaS-providers. For example, in the private cloud of one of the largest western vendors on Linux, more than 90% of instances are running .
At the same time, the open source operating system remains the most popular platform for web hosting. According to the W3Techs analytical agency, 70% of the ten million most popular sites are deployed on Linux servers (according to Alexa ranking ). The remaining 30% belong to Windows.
Experts identify at least two factors that affect the distribution of the operating system in the cloud environment.
Flexibility architecture. This factor in the Linux Foundation is considered one of the determining factors. Linux is suitable for performing diverse tasks and works on platforms of various sizes: from mobile devices to supercomputers. For example, in 2017, 498 supercomputers from the list of the top 500 were running this open source operating system. But by the end of the same year, 100% of the computers in the top started working on Linux.
The most powerful supercomputer to date, IBM's Summit, is managed by Linux . The first exaflops supercomputer in the USA, which is planned to be completed in 2021, will also work on the basis of this open source OS .
Extensive community. The Linux codebase is updated approximately every ten weeks . Since 2005, more than 15 thousand engineers have contributed to the development of the core. Among them are the staff of 200 large corporations. Only in 2017, 3% of changes in the code base were made by developers from Google and Samsung. For 13% of the changes "responsible" in Intel.

Large IT companies are actively involved in the development of both Linux itself and open products based on it. Microsoft offers the Azure Sphere platform for IoT applications, which is based on the Linux kernel. Intel launched the cloud-based project Clear Linux , in which engineers optimize the open-source operating system to run on their processors. HPE offers ClearOS 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 spread of Linux.
The exact figures about the popularity of an operating system in a cloud environment should be treated with a certain degree 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 in mind, it's safe to say that Linux is increasingly being used in the cloud.

“We expect that in the near future Linux may become a leader and bypass other operating systems,” comments Sergey Belkin, head of the project development department at 1cloud.ru . “Considering that just a few years ago, more than half of the virtual machines deployed in our cloud worked on Windows.”
