Virtuozzo Containers is a widespread virtualization platform, that's used to make virtual servers on physical machines. Each VPS created with it is a standalone software emulation of a server, so it has its own Operating System. The system resources are also preset, therefore when you buy a VPS plan with certain disk space, RAM and CPU quotas, they are always at your disposal and won't be shared with another client on the physical server. The Virtuozzo Containers software is really intuitive and user-friendly, so even if you don't have a lot of experience, you'll be able to control your entire server with a web-based graphical interface. With just a couple of clicks, you can start/stop/reboot your virtual machine, set firewall rules, set up server-side software packages and perform numerous maintenance tasks. You can also keep track of the amount of system resources your sites use live and all this data can tell you if you'll need upgrading as you expand your online presence. If needed, you can even reset the entire VPS to its original software setup.
