Virtuozzo Containers is a popular virtualization platform, that is used to set up virtual servers on physical machines. Each VPS created with it is a separate software emulation of a website hosting server, therefore it has its own OS. The resources are also fixed, thus if you get a VPS package with certain CPU, disk space and RAM quotas, they will always be available and will not be shared with another client on the physical server. The Virtuozzo Containers software is exceptionally intuitive and convenient to use, so even if you do not have much experience, you can manage the whole server with a web-based graphical interface. With a few clicks, you will be able to start/stop/reboot your virtual machine, manage firewall rules, set up server-side software and perform many different maintenance tasks. You can also monitor how much resources your Internet sites use live and all this information can inform you if you will need an upgrade as you expand your online presence. When needed, you'll be able to even reset the entire VPS to its original software installation.
