Virtuozzo Containers is a popular virtualization platform, that's used to generate virtual servers on physical machines. Every VPS made with it is an independent software emulation of a hosting server, therefore it has its own OS. The system resources are also predefined, which means that when you acquire a VPS plan with certain CPU, RAM and disk space allocations, they will always be readily available and will not be shared with any other user on the server. The Virtuozzo Containers software is exceptionally intuitive and user-friendly, so even if you don't have a lot of experience, you will be able to control your entire server with a web-based graphical interface. With a few clicks, you will be able to start/stop/reboot the virtual machine, set firewall rules, install server-side software programs and perform numerous maintenance tasks. You can also watch what amount of resources your sites are using in real time and all this info will inform you whether you will need upgrading as you expand your world-wide web presence. When needed, you'll be able to even reset the entire VPS to its original software configuration.
