Virtuozzo Containers is a widespread virtualization platform, that is used to create virtual servers on physical machines. Every VPS created with it is a standalone software emulation of a website hosting server, which means that it has its own OS. The system resources are also predefined, therefore if you get a VPS package with certain disk space, CPU and RAM allocations, they are always at your disposal and won't be shared with another customer on the physical server. The Virtuozzo Containers software is particularly intuitive and convenient to use, so even if you do not have much experience, you'll be able to manage the whole server using a web-based graphical interface. With only a few clicks, you'll be able to start/stop/reboot the virtual machine, manage firewall rules, set up server-side software packages and do plenty of maintenance tasks. You may also keep track of how much system resources your Internet sites use live and all of this info will tell you if you will need an upgrade when you expand your web presence. When needed, you are able to even reset the whole VPS to its original software setup.
