Virtuozzo Containers is a popular virtualization platform, that is used to set up virtual servers on physical machines. Every VPS created with it is a separate software emulation of a server, therefore it has its own OS. The system resources are also fixed, which means that when you purchase a VPS package with certain disk space, RAM and CPU quotas, they are always at your disposal and will not be shared with some other user on the physical server. The Virtuozzo Containers software is particularly intuitive and convenient to use, so even if you don't have a lot of experience, you can control the entire server through a web-based graphical interface. With only 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 number of maintenance tasks. You may also keep track of how much resources your sites use live and this information can inform you whether you should have an upgrade as you expand your world-wide web presence. When needed, you will be able to even reset the whole VPS to its original software configuration.
