Virtuozzo Containers is a popular virtualization platform, that is used to make virtual servers on physical machines. Each VPS created with it is a standalone software emulation of a website hosting server, therefore it has its own Operating System. The system resources are also preset, thus if you order a VPS plan with certain CPU, RAM and disk space quotas, they'll always be readily available and won't be shared with some other user 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 your entire server using a web-based graphical interface. With only a few clicks, you will be able to start/stop/reboot the virtual machine, set firewall rules, set up server-side software and perform a variety of maintenance tasks. You may also monitor how much resources your sites use live and this data will show you if you should have an upgrade when you expand your world-wide web presence. If needed, you are able to even reset the whole VPS to its original software configuration.
