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 independently of one another, so each of them can have its own OS and a fixed and warranted amount of system resources, which include CPU time, disk space, physical memory, et cetera. You're able to start, stop or restart the server, to install many different software packages, to do a variety of maintenance tasks, to create firewall rules and even to reset the entire server to its initial state by using a very user-friendly web interface. In addition, you can keep close track of the used and the available resources and on the running processes, so as to have an idea when the eventual development of your web sites will require a package upgrade as well. Virtuozzo will provide you with complete control of your VPS and you will be able to control everything without difficulty, even if you do not have much experience.
