What is Ubuntu and why is it used so much on servers?

Ubuntu es una distribución Linux: reúne el kernel, herramientas, programas y un método de actualización. Una explicación sencilla con un ejemplo visual, cuándo sirve y qué conviene tener en cuenta.
If you rent a server, you will likely find Ubuntu among the options. It is no coincidence: it makes it easy to install and maintain applications without needing a screen connected to the machine.
In short: Ubuntu is a Linux distribution: it brings together the kernel, tools, programs, and an update method.
Understanding it with an example
Think of it as a complete car: Linux is a central piece, but to drive you also need controls, components, and maintenance. Ubuntu brings those pieces together into a ready-to-use system.
How it works in practice
On a server you can create users, configure a network, install services, and manage it remotely. LTS editions prioritize a long maintenance cycle, although you should always check the support dates for each version.

When it makes sense and what to keep in mind
It is not the only path. Debian and other distributions also work very well. The reasonable thing is to choose based on compatibility, maintenance, and team experience.
How it relates to ArduMaker
In ArduMaker, Linux environments are used to host applications and services; understanding Ubuntu allows you to know what is behind many panel tasks.
Summary
Ubuntu is a Linux distribution: it brings together the kernel, tools, programs, and an update method. What matters is not learning all the names by heart, but understanding what problem it solves and recognizing when you need it.
What is the difference between Ubuntu Desktop and Ubuntu Server?
The two editions share a technical base, but are designed for different uses. Desktop includes a graphical environment ready to work with windows, browser, and desktop applications. Server is normally installed without a full desktop and is oriented toward running services.
That does not make one edition have a "magically more powerful" kernel. What mainly changes are the initial packages, available tools, and intended use.
On a VPS, where it is common to manage everything remotely, it usually does not make sense to dedicate resources to a graphical interface that no one will open.
What does Ubuntu LTS mean?
LTS stands for Long Term Support, or long-term support. Some Ubuntu versions are designed to receive maintenance for extended periods. This matters because a server can host an application for years.
But beware: LTS does not mean you can forget about updating forever. It is advisable to review the support cycle of the installed version and plan migrations before it goes out of maintenance.
How are programs installed?
Ubuntu uses Debian's package system and tools like apt. Instead of searching for a different installer on any website, you can request programs from configured repositories.
For example, sudo apt update updates the information of available packages and sudo apt upgrade attempts to update installed packages according to system policies.
That does not mean running any command found on the Internet is safe. Especially on a server, you need to understand what it installs and where it gets it from.
Ubuntu or Debian?
Debian usually attracts those looking for a conservative and widely tested base. Ubuntu is based on Debian and adds its own decisions, release cycles, and tool integration.
There is no universal answer. If an application requires a specific system version, compatibility matters more than personal preference. And if your team knows a distribution well, that knowledge is also a resource.
When is Ubuntu not convenient for you?
You may need a different system due to a specific application, company policies, support tools, or hardware requirements. Ubuntu is popular, but not mandatory.
Important: a distribution is not just a wallpaper. It also determines how you install programs, receive updates, and maintain the machine throughout its useful life.
