Virtuozzo Containers is a popular virtualization platform, that is used to create virtual servers on physical machines. Each VPS created with it is an independent software emulation of a server, therefore it has its own OS. The system resources are also preset, therefore when you obtain a VPS plan with certain CPU, disk space and RAM quotas, they will always be at your disposal and will not be shared with another user on the physical server. The Virtuozzo Containers software is particularly intuitive and easy to use, so even if you do not have a lot of experience, you can manage the entire server using a web-based graphical interface. With just a couple of clicks, you can easily start/stop/reboot the virtual machine, set firewall rules, install server-side software and perform various maintenance tasks. You can also track how much system resources your web sites use live and all of this info can tell you if you should have an upgrade when you expand your world-wide web presence. If needed, you'll be able to even reset the whole VPS to its original software configuration.
