Virtuozzo Containers is a popular virtualization platform, that is used to make virtual servers on physical machines. Every VPS created with it is a separate software emulation of a website hosting server, so it has its own OS. The system resources are also predefined, so if you buy a VPS plan with certain CPU, disk space and RAM quotas, they are always available and will not be shared with any other user on the server. The Virtuozzo Containers software is exceptionally intuitive and easy to use, so even if you don't have much experience, you can control the entire server with a web-based graphical interface. With only a few clicks, you can easily start/stop/reboot your virtual machine, manage firewall rules, install server-side software applications and perform plenty of maintenance tasks. You can also watch how much system resources your Internet sites use in real time and all of this information can tell you whether you will need upgrading as you expand your world-wide web presence. When needed, you will be able to even reset the whole VPS to its original software installation.
