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, so it has its own Operating System. The resources are also predefined, thus if you buy a VPS package with certain disk space, RAM and CPU allocations, they'll always be at your disposal and won't be shared with some other customer on the physical server. The Virtuozzo Containers software is exceptionally intuitive and easy to use, so even if you don't have much experience, you can control the entire server using a web-based graphical interface. With a couple of clicks, you'll be able to start/stop/reboot your virtual machine, manage firewall rules, install server-side software and do a range of maintenance tasks. You may also track the amount of resources your websites are using live and this data will inform you if you need an upgrade while you expand your web presence. When needed, you'll be able to even reset the whole VPS to its original software configuration.
