Virtuozzo Containers is a widely used virtualization platform, which is used to generate virtual servers on physical machines. Each VPS created with it is a separate software emulation of a server, which means that it has its own OS. The resources are also fixed, which means that when you purchase a VPS package with certain CPU, disk space and RAM allocations, they are always at your disposal and won't be shared with any other user on the server. The Virtuozzo Containers software is exceptionally intuitive and convenient to use, so even if you do not have a lot of experience, you will be able to control the entire server with a web-based graphical interface. With a few clicks, you will be able to start/stop/reboot the virtual machine, manage firewall rules, set up server-side software programs and perform various maintenance tasks. You can also monitor what amount of system resources your web sites use in real time and all this info can tell you if you need an upgrade when you expand your world-wide web presence. When needed, you're able to even reset the whole VPS to its original software installation.
