Virtuozzo Containers is a widespread virtualization platform, which is used to make virtual servers on physical machines. Every VPS made with it is an independent software emulation of a server, so it has its own Operating System. The system resources are also predefined, which means that when you buy a VPS plan with certain CPU, disk space and RAM quotas, they'll always be available and won't be shared with any other client on the server. The Virtuozzo Containers software is exceptionally intuitive and user-friendly, so even if you do not have much experience, you can manage your entire server using a web-based graphical interface. With only a few clicks, you can start/stop/reboot the virtual machine, manage firewall rules, install server-side software applications and perform a number of maintenance tasks. You may also monitor what amount of resources your web sites use live and all this information will show you if you'll need an upgrade when you expand your world-wide web presence. If needed, you'll be able to even reset the entire VPS to its original software setup.
