Virtuozzo Containers is a widely used virtualization platform, that's 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 system resources are also preset, therefore when you buy a VPS plan with certain CPU, RAM and disk space quotas, they are always at your disposal and won't be shared with some other customer on the server. The Virtuozzo Containers software is exceptionally intuitive and easy to use, so even if you don't have a lot of experience, you can manage the whole server using a web-based graphical interface. With only a few clicks, you can start/stop/reboot your virtual machine, set firewall rules, set up server-side software programs and perform a variety of maintenance tasks. You may also keep track of how much system resources your web sites use in real time and this data will inform you whether you'll need upgrading when you expand your online presence. When needed, you'll be able to even reset the whole VPS to its original software configuration.
