Virtuozzo Containers is a widespread virtualization platform, that's used to set up virtual servers on physical machines. Every VPS created with it is a separate software emulation of a website hosting server, so it has its own OS. The system resources are also fixed, therefore when you buy a VPS package with certain CPU, disk space and RAM quotas, they'll always be at your disposal and will not be shared with another client on the server. The Virtuozzo Containers software is very intuitive and easy to use, so even if you do not have much experience, you'll be able to manage the entire server through a web-based graphical interface. With only a couple of clicks, you'll be able to start/stop/reboot the virtual machine, manage firewall rules, install server-side software packages and do plenty of maintenance tasks. You may also watch how much resources your websites are using in real time and all of this data can show you if you will need an upgrade when you expand your world-wide web presence. When needed, you're able to even reset the whole VPS to its original software installation.
