Virtuozzo Containers is a software solution, that is used to make virtual servers on a physical hosting server. It allows VPS accounts to be generated and controlled separately of one another, so each can have its unique OS and a fixed and warranted volume of system resources, for instance CPU time, disk space, physical memory, et cetera. You can stop, start or reboot the server, to install different software packages, to do many different maintenance tasks, to create firewall rules and even to reboot the entire server to its initial state by using a very intuitive web interface. You may also keep close track of the used and the available resources and on the active processes, in order to have an idea whether the eventual development of your websites will require a plan upgrade too. Virtuozzo gives you complete control of your VPS and you can control everything without difficulty, even when you don't have much experience.
