Virtuozzo Containers is a popular virtualization platform, that is used to make virtual servers on physical machines. Every VPS made with it is a separate software emulation of a website hosting server, which means that it has its own Operating System. The system resources are also fixed, which means that when you purchase a VPS plan with certain disk space, CPU and RAM quotas, they'll always be available and won't be shared with some other user on the physical server. The Virtuozzo Containers software is really intuitive and user-friendly, 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 just a couple of clicks, you can start/stop/reboot your virtual machine, set firewall rules, install server-side software applications and perform a range of maintenance tasks. You can also keep track of what amount of resources your websites are using live and this info will inform you whether you should have upgrading as you expand your online presence. When needed, you are able to even reset the whole VPS to its original software installation.
