Virtuozzo Containers is a popular virtualization platform, that is used to generate virtual servers on physical machines. Every VPS made with it is an independent software emulation of a server, therefore it has its own Operating System. The resources are also predefined, thus if you order a VPS package with certain disk space, CPU and RAM allocations, they're always at your disposal and will not 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 the entire server with a web-based graphical interface. With a few clicks, you will be able to start/stop/reboot your virtual machine, set firewall rules, set up server-side software and do a variety of maintenance tasks. You can also track the amount of resources your Internet sites use in real time and all this information will show you whether you should have an upgrade when you expand your web presence. If needed, you will be able to even reset the whole VPS to its original software configuration.
