Virtuozzo Containers is a widely used virtualization platform, that is used to set up virtual servers on physical machines. Every VPS created with it is a separate software emulation of a hosting server, which means that it has its own Operating System. The system resources are also preset, thus when you get a VPS plan with certain disk space, CPU and RAM allocations, they are always readily available and won't be shared with any other client on the physical server. The Virtuozzo Containers software is very intuitive and user-friendly, so even if you don't have a lot of experience, you can control your entire server with a web-based graphical interface. With just a couple of clicks, you can easily start/stop/reboot your virtual machine, set firewall rules, install server-side software packages and perform various maintenance tasks. You may also track how much system resources your sites are using live and this info will inform you whether you will need upgrading when you expand your web presence. When needed, you'll be able to even reset the whole VPS to its original software setup.
