Virtuozzo Containers is a widespread virtualization platform, that is used to create virtual servers on physical machines. Each VPS created with it is a separate software emulation of a server, so it has its own OS. The system resources are also predefined, thus if you order a VPS package with certain CPU, RAM and disk space allocations, they're always available to you and won't be shared with some other client on the server. The Virtuozzo Containers software is truly intuitive and user-friendly, so even if you don't have much experience, you can manage the whole server using a web-based graphical interface. With a few clicks, you can easily start/stop/reboot your virtual machine, set firewall rules, set up server-side software and perform a range of maintenance tasks. You may also monitor the amount of system resources your sites use live and this data can inform you if you'll need upgrading as you expand your web presence. When needed, you'll be able to even reset the entire VPS to its original software setup.
