From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Where did you find that azure runs on linux?

I dont know of anywhere that Microsoft confirms, officially, that Azure, itself, is largely running on Linux. They share stats about what workloads others are running on it, but not, to my knowledge, about what it is composed of.

I suppose that would be an oversimplification, anyway.

But that Azure itself is running mostly on Linux is an open secret among folks who spend time chatting with engineers who have worked on the framework of the Azure cloud.

When I have chatted with them, Azure cloud engineers have displayed huge amouts of Linux experience while they sometimes needed to "phone a friend" to answer Windows server edition questions.

For a variety of reasons related to how much longer people have been scaling Linux clusters, than Windows servers, this isn't particularly shocking.
