Virtuozzo Containers is a popular virtualization platform, that is used to create 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 system resources are also preset, which means that when you order a VPS plan with certain disk space, RAM and CPU allocations, they're always readily available and will not be shared with some other customer on the physical server. The Virtuozzo Containers software is exceptionally intuitive and easy to use, so even if you do not have much experience, you will be able to manage the whole server through a web-based graphical interface. With a couple of clicks, you can easily start/stop/reboot your virtual machine, manage firewall rules, install server-side software applications and perform numerous maintenance tasks. You can also track how much system resources your sites use live and this information will inform you if you'll need an upgrade when you expand your online presence. If needed, you are able to even reset the whole VPS to its original software configuration.
