Virtuozzo Containers is a widespread virtualization platform, which is used to set up virtual servers on physical machines. Every 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 buy a VPS package with certain CPU, RAM and disk space allocations, they'll always be readily available and won't be shared with any other user on the server. The Virtuozzo Containers software is exceptionally intuitive and convenient to use, so even if you do not have a lot of experience, you'll be able to manage the entire server with a web-based graphical interface. With just a couple of clicks, you will be able to start/stop/reboot the virtual machine, set firewall rules, set up server-side software and do various maintenance tasks. You can also monitor the amount of resources your web sites use live and all of this data can tell you if you need an upgrade as you expand your web presence. When needed, you'll be able to even reset the whole VPS to its original software configuration.
