Virtuozzo Containers is a widespread virtualization platform, that is used to set up virtual servers on physical machines. Every VPS created with it is a standalone software emulation of a website hosting server, therefore it has its own OS. The system resources are also fixed, so if you order a VPS plan with certain CPU, disk space and RAM allocations, they will always be at your disposal and won't be shared with any other client on the server. The Virtuozzo Containers software is really 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 just a couple of clicks, you can easily start/stop/reboot the virtual machine, manage firewall rules, set up server-side software and do various maintenance tasks. You can also track how much system resources your sites use in real time and this information will inform you if you'll need an upgrade when you expand your web presence. When needed, you're able to even reset the entire VPS to its original software configuration.
