Virtuozzo Containers is a widespread virtualization platform, that is used to generate virtual servers on physical machines. Each VPS made with it is an independent software emulation of a server, therefore it has its own Operating System. The system resources are also predefined, which means that if you obtain a VPS plan with certain disk space, RAM and CPU quotas, they are always available and won't be shared with some other client on the server. The Virtuozzo Containers software is really intuitive and user-friendly, so even if you don't have much experience, you will be able to manage the entire server through a web-based graphical interface. With only a few clicks, you can start/stop/reboot the virtual machine, set firewall rules, install server-side software packages and do numerous maintenance tasks. You can also monitor what amount of system resources your websites use in real time and all this data can tell you if you will need upgrading as you expand your world-wide web presence. When needed, you are able to even reset the entire VPS to its original software installation.
