What is Ubuntu VPS?

An “Ubuntu VPS” refers to a Virtual Private Server that is running the Ubuntu operating system. Let’s break down these terms:

1. Virtual Private Server (VPS)

A VPS is a virtualized server that operates within a larger physical server. It is created through a process called virtualization, which partitions a single physical server into multiple virtual servers, each with its dedicated resources (CPU, RAM, storage, etc.).

VPS hosting is a cost-effective way to have more control and resources compared to shared hosting, while still being more affordable than a dedicated server.

2. Ubuntu

Ubuntu is a popular open-source Linux distribution (or operating system) based on Debian. It is known for its user-friendliness, stability, and strong community support.

Ubuntu is often used for various purposes, including desktop computing and server environments.

So, when someone refers to a “Ubuntu VPS”, they are essentially talking about a virtual server that runs the Ubuntu operating system.

This setup is commonly used for hosting websites, web applications, databases, and various online services, as it provides a balance of affordability, customization, and performance.

Users can remotely manage and configure their Ubuntu VPS to suit their specific hosting needs. Stay with us so that we can introduce you to the method of setting up and managing the Ubuntu server vps.
