Virtuozzo Containers is a widely used virtualization platform, that is used to generate virtual servers on physical machines. Every VPS made with it is an independent software emulation of a hosting server, therefore it has its own Operating System. The system resources are also fixed, therefore when you buy a VPS package with certain disk space, CPU and RAM allocations, they are always at your disposal and will not 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 a lot of experience, you can control your entire server using a web-based graphical interface. With just a couple of clicks, you can easily start/stop/reboot your virtual machine, manage firewall rules, install server-side software and perform a variety of maintenance tasks. You may also keep track of how much system resources your websites use live and this info will inform you if you'll need an upgrade as you expand your world-wide web presence. If needed, you'll be able to even reset the whole VPS to its original software setup.
