Virtuozzo Containers is software, which is used to make virtual servers on a physical server. It allows VPS accounts to be generated and controlled independently of each other, so each of them can have its own OS and a fixed and guaranteed quantity of system resources, such as CPU time, disk space, physical memory, and so on. You can start, stop or restart the server, to set up a variety of software packages, to perform numerous maintenance tasks, to set up firewall rules and even to reboot the entire server to its initial state through a very user-friendly web interface. You may also keep close track of the used and the available resources and on the running processes, to have an idea if the eventual development of your Internet sites will require a package upgrade as well. Virtuozzo provides you with full control over your VPS and you'll be able to manage everything easily, even when you do not have much experience.
