Virtuozzo Containers is a widely used virtualization platform, which is used to generate virtual servers on physical machines. Each VPS made with it is an independent software emulation of a server, therefore it has its own OS. The resources are also preset, so if you purchase a VPS plan with certain disk space, RAM and CPU quotas, they're always readily available and will not be shared with any other customer on the server. The Virtuozzo Containers software is really intuitive and convenient to use, so even if you do not have a lot of experience, you'll be able to manage your entire server with a web-based graphical interface. With just a few clicks, you can easily start/stop/reboot the virtual machine, set firewall rules, install server-side software packages and perform a number of maintenance tasks. You can also watch how much system resources your websites use live and this information will inform you if you'll need upgrading when you expand your world-wide web presence. If needed, you are able to even reset the entire VPS to its original software installation.
