Virtuozzo Containers is a widely used virtualization platform, which is used to create virtual servers on physical machines. Each VPS created with it is a standalone software emulation of a server, so it has its own Operating System. The system resources are also fixed, therefore when you buy a VPS package with certain CPU, RAM and disk space quotas, they'll always be available and will not be shared with some other customer on the server. The Virtuozzo Containers software is really intuitive and easy to use, so even if you don't have a lot of experience, you can control the whole server using a web-based graphical interface. With only a couple of clicks, you can start/stop/reboot the virtual machine, manage firewall rules, install server-side software applications and perform a variety of maintenance tasks. You may also track the amount of resources your sites use live and all this info can inform you whether you should have upgrading as you expand your world-wide web presence. When needed, you can even reset the whole VPS to its original software configuration.
