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 website hosting server, therefore it has its own Operating System. The system resources are also predefined, which means that when you acquire a VPS package with certain CPU, disk space and RAM allocations, they're always readily available and won't be shared with another user on the server. The Virtuozzo Containers software is particularly intuitive and easy to use, so even if you don't have a lot of experience, you can control the whole server using a web-based graphical interface. With only a couple of clicks, you can easily start/stop/reboot your virtual machine, set firewall rules, install server-side software applications and do a number of maintenance tasks. You may also keep track of the amount of system resources your web sites are using in real time and this information will inform you whether you'll need upgrading when you expand your world-wide web presence. When needed, you're able to even reset the whole VPS to its original software setup.
