Virtuozzo Containers is a widespread virtualization platform, that's used to create virtual servers on physical machines. Each VPS created with it is a standalone software emulation of a website hosting server, so it has its own Operating System. The resources are also predefined, so when you purchase a VPS package with certain disk space, CPU and RAM quotas, they will always be at your disposal and won't be shared with some other user on the physical server. The Virtuozzo Containers software is truly intuitive and user-friendly, so even if you don't have a lot of experience, you'll be able to control the entire server with a web-based graphical interface. With just a couple of clicks, you can easily start/stop/reboot the virtual machine, set firewall rules, install server-side software and do various maintenance tasks. You can also keep track of the amount of resources your sites are using live and this data can show you if you should have an upgrade while you expand your web presence. If needed, you are able to even reset the whole VPS to its original software configuration.
