Virtuozzo Containers is a popular virtualization platform, that's used to make virtual servers on physical machines. Each VPS created with it is a standalone software emulation of a hosting server, so it has its own OS. The system resources are also fixed, which means that when you get a VPS package with certain disk space, CPU and RAM quotas, they will always be available and will not be shared with another user on the physical server. The Virtuozzo Containers software is exceptionally intuitive and easy to use, so even if you don't have much experience, you can control your entire server using a web-based graphical interface. With a few clicks, you can easily start/stop/reboot the virtual machine, set firewall rules, set up server-side software packages and perform a variety of maintenance tasks. You may also keep track of how much system resources your websites use in real time and all this data can show you if you need upgrading while you expand your world-wide web presence. If needed, you'll be able to even reset the whole VPS to its original software installation.
