Virtuozzo Containers is a popular virtualization platform, that is used to generate virtual servers on physical machines. Each VPS made with it is an independent software emulation of a website hosting server, so it has its own Operating System. The system resources are also fixed, which means that if you buy a VPS package with certain disk space, CPU and RAM quotas, they'll always be available and won't be shared with another client on the physical server. The Virtuozzo Containers software is truly intuitive and convenient to use, so even if you don't have much experience, you'll be able to control the entire server with a web-based graphical interface. With just a few clicks, you'll be able to start/stop/reboot your virtual machine, set firewall rules, install server-side software programs and do many different maintenance tasks. You can also keep track of how much system resources your web sites use in real time and all of this information will show you whether you should have an upgrade when you expand your web presence. If needed, you'll be able to even reset the whole VPS to its original software setup.
