Virtuozzo Containers is a widely used virtualization platform, that is used to create virtual servers on physical machines. Each VPS made with it is a separate software emulation of a server, therefore it has its own OS. The resources are also preset, which means that if you get a VPS package with certain CPU, RAM and disk space allocations, they will always be available and won't be shared with any other user on the physical server. The Virtuozzo Containers software is truly intuitive and user-friendly, so even if you do not have a lot of experience, you will be able to control the entire server with a web-based graphical interface. With a few clicks, you can easily start/stop/reboot the virtual machine, set firewall rules, set up server-side software packages and do many different maintenance tasks. You may also watch how much system resources your web sites use live and all of this info can inform you whether you need an upgrade as you expand your world-wide web presence. If needed, you'll be able to even reset the entire VPS to its original software installation.
