Virtuozzo Containers is a widely used virtualization platform, that is used to create virtual servers on physical machines. Every VPS made with it is an independent software emulation of a website hosting server, which means that it has its own OS. The resources are also predefined, so when you buy a VPS plan with certain CPU, RAM and disk space quotas, they'll always be available to you and will not be shared with another client on the physical server. The Virtuozzo Containers software is particularly intuitive and convenient to use, so even if you do not have a lot of experience, you'll be able to manage the entire server using a web-based graphical interface. With only a couple of clicks, you'll be able to start/stop/reboot the virtual machine, manage firewall rules, install server-side software and perform various maintenance tasks. You may also keep track of how much resources your Internet sites are using in real time and this info can tell you whether you should have an upgrade when you expand your web presence. If needed, you're able to even reset the whole VPS to its original software installation.
