Virtuozzo Containers is a widespread virtualization platform, that's used to create virtual servers on physical machines. Every VPS created with it is a separate software emulation of a server, so it has its own OS. The resources are also predefined, thus if you acquire a VPS plan with certain CPU, disk space and RAM allocations, they are always readily available and won't be shared with some other client on the server. The Virtuozzo Containers software is very intuitive and convenient to use, so even if you don't have much experience, you can control your entire server through a web-based graphical interface. With a couple of clicks, you can easily start/stop/reboot the virtual machine, set firewall rules, set up server-side software applications and perform a number of maintenance tasks. You can also keep track of what amount of system resources your web sites are using live and all of this data can tell you if you will need an upgrade when you expand your web presence. When needed, you can even reset the whole VPS to its original software configuration.
