Virtuozzo Containers is a popular virtualization platform, which is used to generate 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 Operating System. The system resources are also preset, therefore if you get a VPS package with certain disk space, CPU and RAM quotas, they'll always be available to you and won't be shared with another user on the server. The Virtuozzo Containers software is particularly intuitive and user-friendly, so even if you do not have much experience, you can manage the entire server using a web-based graphical interface. With only a few clicks, you'll be able to start/stop/reboot the virtual machine, set firewall rules, set up server-side software and perform many different maintenance tasks. You can also track what amount of resources your sites use live and all of this data can inform you if you'll need upgrading while you expand your web presence. If needed, you are able to even reset the entire VPS to its original software configuration.
