Virtuozzo Containers is a popular virtualization platform, that's used to create virtual servers on physical machines. Every VPS created with it is an independent software emulation of a hosting server, so it has its own Operating System. The resources are also preset, thus when you buy a VPS package with certain CPU, disk space and RAM quotas, they will always be available and won't be shared with any other client on the physical server. The Virtuozzo Containers software is truly intuitive and convenient to use, so even if you don't have much experience, you will be able to control the whole server through a web-based graphical interface. With a few clicks, you'll be able to start/stop/reboot the virtual machine, set firewall rules, install server-side software packages and perform a number of maintenance tasks. You can also track what amount of system resources your websites use in real time and all this info will show you whether you'll need upgrading when you expand your web presence. If needed, you are able to even reset the whole VPS to its original software setup.
