Virtuozzo Containers is a popular virtualization platform, that is used to generate virtual servers on physical machines. Every VPS made with it is a standalone software emulation of a website hosting server, therefore it has its own OS. The resources are also fixed, therefore when you buy a VPS plan with certain disk space, RAM and CPU quotas, they'll always be available and will not be shared with any other user on the physical server. The Virtuozzo Containers software is very intuitive and user-friendly, so even if you don't have a lot of experience, you will be able to control your entire server through a web-based graphical interface. With just a few clicks, you'll be able to start/stop/reboot the virtual machine, manage firewall rules, set up server-side software packages and do a number of maintenance tasks. You may also keep track of the amount of resources your sites are using live and this info will inform you if you need an upgrade when you expand your world-wide web presence. If needed, you can even reset the entire VPS to its original software setup.
