Virtuozzo Containers is a widespread virtualization platform, that is used to generate virtual servers on physical machines. Every VPS made with it is a separate software emulation of a hosting server, therefore it has its own Operating System. The system resources are also predefined, so if you order a VPS package with certain disk space, RAM and CPU quotas, they're always available to you and won't be shared with another user on the server. The Virtuozzo Containers software is very intuitive and user-friendly, so even if you don't have much experience, you can manage your entire server using a web-based graphical interface. With a few clicks, you will be able to start/stop/reboot your virtual machine, manage firewall rules, set up server-side software and perform many different maintenance tasks. You may also watch what amount of resources your websites use live and all of this information can tell you if you'll need an upgrade when you expand your online presence. If needed, you will be able to even reset the whole VPS to its original software setup.
