Virtuozzo Containers is a popular virtualization platform, that's used to generate virtual servers on physical machines. Each VPS made with it is a standalone software emulation of a hosting server, which means that it has its own OS. The system resources are also fixed, thus when you buy a VPS plan with certain disk space, CPU and RAM allocations, they'll always be at your disposal and won't be shared with any other client on the physical server. The Virtuozzo Containers software is truly intuitive and user-friendly, so even if you don't have a lot of experience, you can manage the whole server using a web-based graphical interface. With a few clicks, you will be able to start/stop/reboot your virtual machine, manage firewall rules, set up server-side software packages and do a variety of maintenance tasks. You may also track the amount of system resources your web sites use live and all this info will tell you if you'll need an upgrade while you expand your online presence. When needed, you'll be able to even reset the whole VPS to its original software configuration.
