Virtuozzo Containers is a popular virtualization platform, that's used to make virtual servers on physical machines. Every VPS created with it is an independent software emulation of a hosting server, which means that it has its own OS. The system resources are also predefined, so if you order a VPS plan with certain CPU, RAM and disk space quotas, they'll always be readily available and won't be shared with another user on the server. The Virtuozzo Containers software is truly intuitive and user-friendly, so even if you don't have a lot of experience, you can manage your entire server using a web-based graphical interface. With just a few clicks, you can start/stop/reboot your virtual machine, set firewall rules, set up server-side software programs and do many different maintenance tasks. You may also keep track of how much system resources your sites are using in real time and this info can tell you if you need an upgrade when you expand your world-wide web presence. When needed, you are able to even reset the whole VPS to its original software setup.
