Virtuozzo Containers is a popular virtualization platform, that is used to generate virtual servers on physical machines. Each VPS created 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, thus when you purchase a VPS plan with certain CPU, disk space and RAM quotas, they're always available and will not be shared with some other user on the server. The Virtuozzo Containers software is very intuitive and convenient to use, so even if you do not have much experience, you can control the entire server using a web-based graphical interface. With just a few clicks, you can start/stop/reboot the virtual machine, manage firewall rules, install server-side software programs and do numerous maintenance tasks. You can also keep track of the amount of resources your sites are using in real time and this info can inform you whether you should have an upgrade while you expand your world-wide web presence. When needed, you can even reset the entire VPS to its original software installation.
