Virtuozzo Containers is a widely used virtualization platform, that is used to generate virtual servers on physical machines. Each VPS made with it is a standalone software emulation of a server, therefore it has its own OS. The system resources are also preset, so if you acquire a VPS plan with certain CPU, disk space and RAM quotas, they're always available to you and won't be shared with another customer on the physical server. The Virtuozzo Containers software is very intuitive and user-friendly, so even if you don't have much experience, you can manage your entire server through a web-based graphical interface. With just a couple of clicks, you can start/stop/reboot the virtual machine, manage firewall rules, set up server-side software programs and perform a number of maintenance tasks. You may also monitor how much system resources your Internet sites use in real time and all this data can show you if you will need upgrading as you expand your world-wide web presence. If needed, you'll be able to even reset the whole VPS to its original software configuration.
