Virtuozzo Containers is a popular virtualization platform, which is used to make virtual servers on physical machines. Every VPS made with it is a separate software emulation of a hosting server, which means that it has its own OS. The system resources are also fixed, thus if you acquire a VPS plan with certain CPU, disk space and RAM allocations, they are always at your disposal and won't be shared with any other client on the server. The Virtuozzo Containers software is really intuitive and easy to use, so even if you don't have much experience, you'll be able to manage the entire server with a web-based graphical interface. With only a couple of clicks, you can easily start/stop/reboot the virtual machine, set firewall rules, set up server-side software packages and do a number of maintenance tasks. You can also watch the amount of resources your web sites use live and all of this information can inform you whether you will need upgrading when you expand your web presence. When needed, you're able to even reset the whole VPS to its original software setup.
