Virtuozzo Containers is a popular virtualization platform, that is used to set up virtual servers on physical machines. Each VPS made with it is an independent software emulation of a server, therefore it has its own OS. The resources are also preset, so if you get a VPS plan with certain CPU, RAM and disk space allocations, they are always available to you and will not be shared with some other user on the server. The Virtuozzo Containers software is particularly intuitive and easy to use, so even if you do not have much experience, you will be able to manage your entire server with a web-based graphical interface. With only a few clicks, you can start/stop/reboot the virtual machine, set firewall rules, install server-side software applications and do various maintenance tasks. You can also watch what amount of resources your sites use live and all this information will tell you if you need upgrading when you expand your world-wide web presence. If needed, you will be able to even reset the entire VPS to its original software configuration.
