Let's try to understand why Linux has become so successful.
Because it is open source, software companies don't have to spend developing
efforts in the platform anymore, so the platform has become a commodity.
And also the open source nature makes it more secure because the code is accessible to anyone, which makes it easy to
verify its security in case there are any bugs or other features. Any developer can access the code and propose a change.
So you don't have to wait for months anymore before a patch is provided.
You can write it yourself.
Obviously open source is free, so you can save money on it.
And Linux is an operating system that is available for any CPU architecture.
So where is Linux used primarily? You will find it on servers.
It's often used as a web server, a database server or an AI server.
And as such it is often used behind public cloud on the Internet.
You'll also find it as a foundation of containerized applications as well as in embedded devices.
Did you know, for instance, that Android on smartphones is based on Linux? But you
also find it in automotive in media players? The there is only the end user
desktop where it is not dominant, and that is because of Microsoft Office.
Microsoft Office has established itself as the worldwide standard for working
with documents, and there is no Office version for Linux available.
