Virtuozzo Containers is a software solution, which is used to make virtual servers on a physical machine. It allows VPS accounts to be generated and handled separately of each other, so each can have its unique OS and a fixed and warranted amount of system resources, for example CPU time, disk space, physical memory, etc. You are able to stop, start or reboot the server, to install different software packages, to do various maintenance tasks, to create firewall rules and even to reset the entire hosting server to its initial state using a very intuitive world-wide web interface. You can also keep close track of the used and the available system resources and on the running processes, so as to have an idea if the eventual development of your web sites will require a package upgrade too. Virtuozzo will give you complete control over your VPS and you'll be able to manage everything with ease, even when you don't have a lot of experience.
