Virtuozzo Containers is a widespread virtualization platform, that's used to generate virtual servers on physical machines. Each VPS made with it is a separate software emulation of a website hosting server, therefore it has its own Operating System. The system resources are also fixed, which means that if you buy a VPS package with certain disk space, CPU and RAM allocations, they are always available and won't be shared with any other user on the server. The Virtuozzo Containers software is very intuitive and easy to use, so even if you don't have a lot of experience, you can control the whole server through a web-based graphical interface. With a few clicks, you will be able to start/stop/reboot the virtual machine, manage firewall rules, install server-side software applications and do numerous maintenance tasks. You can also track how much system resources your sites use live and all this data will tell you whether you need an upgrade as you expand your world-wide web presence. If needed, you will be able to even reset the entire VPS to its original software configuration.
