What is Ubuntu Server and How to Install it?

Canonical Ltd., the official developer of Ubuntu. It is an operating system distribution that uses the Linux kernel developed for servers. Unlike the versions of Ubuntu for desktop and laptop platforms, Ubuntu Server, which contains some additional features and services, is an operating system distribution that only works on server systems. Ubuntu Server is not a Linux distribution that personal users can install on their PCs.

In addition to being a completely free Linux operating system distribution, Ubuntu is also one of the most preferred operating system versions on the server-side. Ubuntu Server, which is the version of Ubuntu prepared for the server, does not have a user graphical interface, unlike the Ubuntu distribution, and the installation process is performed with the help of the command line.

Ubuntu Server is fully compatible with many systems and platforms. Ubuntu Server distribution is a platform compatible with popular products such as Microsoft Hyper-V and VMware ESX server. With Ubuntu Server, you can easily create the appropriate infrastructure to host websites and game servers on your server.
