Virtuozzo Containers is a popular virtualization platform, which is used to set up virtual servers on physical machines. Each VPS created with it is an independent software emulation of a website hosting server, which means that it has its own OS. The system resources are also preset, so when you buy a VPS package with certain disk space, RAM and CPU allocations, they will always be at your disposal and won't be shared with any other customer on the server. The Virtuozzo Containers software is exceptionally intuitive and convenient to use, so even if you don't have a lot of experience, you can control the entire server through a web-based graphical interface. With only a couple of clicks, you'll be able to start/stop/reboot your virtual machine, manage firewall rules, set up server-side software and do a variety of maintenance tasks. You may also keep track of the amount of system resources your websites are using live and all this info can show you whether you should have upgrading while you expand your world-wide web presence. If needed, you are able to even reset the entire VPS to its original software installation.
