Virtuozzo Containers is a popular virtualization platform, that is used to create virtual servers on physical machines. Every VPS made with it is a separate software emulation of a hosting server, which means that it has its own OS. The system resources are also preset, so if you buy a VPS plan with certain disk space, CPU and RAM quotas, they are always at your disposal and will not be shared with any other client on the physical server. The Virtuozzo Containers software is very intuitive and convenient to use, so even if you do not have much experience, you'll be able to manage the whole server through a web-based graphical interface. With just a couple of clicks, you can easily start/stop/reboot the virtual machine, set firewall rules, install server-side software programs and perform many different maintenance tasks. You may also monitor how much resources your sites are using in real time and all this information will show you whether you'll need an upgrade as you expand your world-wide web presence. When needed, you can even reset the entire VPS to its original software setup.
