Virtuozzo Containers is a widely used virtualization platform, that is used to make virtual servers on physical machines. Each VPS made with it is an independent software emulation of a hosting server, so it has its own Operating System. The resources are also preset, therefore when you buy a VPS plan with certain CPU, RAM and disk space allocations, they'll always be readily available and won't be shared with another client on the physical server. The Virtuozzo Containers software is particularly intuitive and user-friendly, so even if you don't have a lot of experience, you will be able to manage the entire server with a web-based graphical interface. With just a few clicks, you will be able to start/stop/reboot the virtual machine, manage firewall rules, set up server-side software packages and do numerous maintenance tasks. You can also keep track of what amount of resources your sites use live and all of this information can tell you whether you'll need upgrading as you expand your web presence. If needed, you are able to even reset the whole VPS to its original software installation.
