Virtuozzo Containers is a widely used virtualization platform, that's used to create virtual servers on physical machines. Every VPS created with it is an independent software emulation of a hosting server, so it has its own Operating System. The resources are also fixed, which means that if you acquire a VPS plan with certain disk space, CPU and RAM quotas, they'll always be at your disposal and won't be shared with some other client on the physical server. The Virtuozzo Containers software is really intuitive and easy to use, so even if you don't have much experience, you will be able to manage your entire server with 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 and perform numerous maintenance tasks. You may also watch what amount of system resources your sites are using in real time and all this info can show you if you need upgrading while you expand your world-wide web presence. When needed, you can even reset the whole VPS to its original software setup.
