Virtuozzo Containers is a widely used virtualization platform, that's used to set up virtual servers on physical machines. Each VPS made with it is a separate software emulation of a hosting server, therefore it has its own Operating System. The system resources are also preset, therefore when you obtain a VPS plan with certain CPU, RAM and disk space quotas, they are always at your disposal and will not be shared with another customer on the physical server. The Virtuozzo Containers software is very intuitive and easy to use, so even if you do not have a lot of experience, you can manage the whole server using a web-based graphical interface. With just a few clicks, you can easily start/stop/reboot your virtual machine, set firewall rules, set up server-side software and do numerous maintenance tasks. You may also track the amount of resources your sites use live and this data will inform you whether you should have an upgrade as you expand your world-wide web presence. If needed, you'll be able to even reset the whole VPS to its original software installation.
