Virtuozzo Containers is software, that is used to create virtual servers on a physical machine. It allows VPS accounts to be set up and managed separately of one another, so each of them can have its own OS and a fixed and guaranteed amount of system resources, such as CPU time, disk space, physical memory, etc. You are able to start, stop or restart the server, to install different software packages, to perform numerous maintenance tasks, to create firewall rules and even to reset the entire hosting server to its initial state by using a very intuitive online interface. You can also keep track of the used and the available system resources and on the running processes, to have an idea whether the eventual growth of your sites will require a package upgrade as well. Virtuozzo provides you with full control over your VPS and you are able to manage everything without any difficulty, even if you don't have a lot of experience.
