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 independently of each other, so each of them can have its very own OS plus a fixed and warranted amount of resources, for instance CPU time, disk space, physical memory, etc. You will be able to stop, start or reboot the server, to set up different software packages, to perform a variety of maintenance tasks, to set up firewall rules and even to reset the entire hosting server to its original state using a very user-friendly world-wide web interface. You can 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 web sites will require a package upgrade too. Virtuozzo gives you complete control over your VPS and you are able to manage everything easily, even when you don't have a lot of experience.
