Guys, what does the VPS concept we constantly hear about mean? This system, which operates with virtualization, allows a physical server to be divided and transformed into independent virtual machines. How can it be set up, and in which scenarios should it be preferred? Share your experiences.

VPS has this really interesting side to it – like, how is the performance of these virtual machines that can operate independently of a physical server guaranteed?
A VPS (Virtual Private Server) isn't just a split version of a physical server; it's an isolated virtual environment that shares the same server resources. For example, in my test environment, I use a VPS running Prometheus monitoring — its resources never mix with those of neighboring virtual machines, making it highly reliable in terms of isolation.
When it comes to setup, I usually use a shell script on a Debian-based VPS to automate the installation of OpenVPN and Docker. For instance, I can get Docker up and running in 2 minutes with the command `curl -fsSL https://get.docker.com | sh`, and then manage containers through the Portainer interface. For web server scenarios (e.g., Apache/Nginx), to set up a LAMP stack, I start with commands like `apt install apache2 mariadb-server`. In short, you can use a VPS for both personal projects and medium-scale web applications, as long as you configure the necessary tools properly.
How can I set up a VPS securely, for example, how do I lock down SSH access as quickly as possible?
