Virtuozzo Containers is a widespread virtualization platform, that's used to make virtual servers on physical machines. Each VPS created with it is a standalone software emulation of a server, so it has its own OS. The resources are also preset, thus when you obtain a VPS package with certain disk space, CPU and RAM quotas, they are always at your disposal and won't be shared with some other user on the server. The Virtuozzo Containers software is very intuitive and convenient to use, so even if you don't have a lot of experience, you will be able to manage your entire server with a web-based graphical interface. With just a few clicks, you can start/stop/reboot your virtual machine, manage firewall rules, set up server-side software and perform a number of maintenance tasks. You can also monitor how much system resources your sites are using in real time and all of this info will tell you if you need upgrading as you expand your web presence. If needed, you are able to even reset the entire VPS to its original software configuration.
