Virtuozzo Containers is a widely used virtualization platform, that's used to make virtual servers on physical machines. Each VPS created with it is a separate software emulation of a server, so it has its own Operating System. The resources are also predefined, which means that if you obtain a VPS package with certain CPU, RAM and disk space quotas, they will always be at your disposal and will not be shared with some other client on the physical server. The Virtuozzo Containers software is exceptionally intuitive and user-friendly, so even if you don't have much experience, you can manage your entire server through a web-based graphical interface. With a couple of clicks, you'll be able to start/stop/reboot your virtual machine, set firewall rules, set up server-side software programs and do a range of maintenance tasks. You can also watch how much system resources your web sites use live and all of this data will show you if you'll need an upgrade while you expand your online presence. If needed, you can even reset the whole VPS to its original software installation.
