5 Best free to use Linux Server distributions for 2023

Linux is an open-source software platform developed initially for home computers but later become a dominant Server operating system. Linux Server OS are popular because of their small size and ability to quickly convert to perform some specific operations such as Web server, File server, monitoring tool, etc. That’s why you will see almost all computing cloud platforms prefer Linux servers to distribute their computing services.

Apart from powring thousands of racks at hosting companies, in server farms, and at cloud providers, you can also see Linux command line servers nested in container instances or virtual machines, in short Linux keeps the Internet alive. As a server, Linux today supports more architectures and processors than any other kernel – from very large to very small.
