Virtuozzo Containers is a widespread virtualization platform, that is used to make virtual servers on physical machines. Each VPS made with it is a standalone software emulation of a hosting server, therefore it has its own OS. The system resources are also predefined, therefore if you get a VPS package with certain disk space, CPU and RAM allocations, they are always available and won't be shared with any other customer on the physical server. The Virtuozzo Containers software is really intuitive and user-friendly, so even if you don't have much experience, you can control the whole server with a web-based graphical interface. With a couple of clicks, you can start/stop/reboot the virtual machine, manage firewall rules, install server-side software packages and do various maintenance tasks. You may also keep track of what amount of system resources your Internet sites are using in real time and this data will show you whether you will need upgrading as you expand your web presence. If needed, you are able to even reset the entire VPS to its original software installation.
