Virtuozzo Containers is a widely used virtualization platform, that's used to set up virtual servers on physical machines. Every VPS created with it is a separate software emulation of a hosting server, so it has its own Operating System. The system resources are also predefined, therefore if you acquire a VPS package with certain CPU, disk space and RAM quotas, they'll always be at your disposal and will not be shared with any 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'll be able to control the entire server using a web-based graphical interface. With a few clicks, you can easily start/stop/reboot the virtual machine, manage firewall rules, set up server-side software and perform a number of maintenance tasks. You may also watch what amount of system resources your websites are using in real time and all this data can tell you whether you need upgrading as you expand your web presence. When needed, you're able to even reset the whole VPS to its original software setup.
