Virtuozzo Containers is a popular virtualization platform, which is used to make virtual servers on physical machines. Every VPS created with it is a separate software emulation of a server, so it has its own Operating System. The resources are also fixed, therefore when you order a VPS package with certain disk space, RAM and CPU allocations, they'll always be at your disposal and will not be shared with some other client on the physical server. The Virtuozzo Containers software is very intuitive and convenient to use, so even if you don't have much experience, you can manage the entire server with a web-based graphical interface. With only a couple of clicks, you can easily start/stop/reboot your virtual machine, manage firewall rules, install server-side software applications and perform a variety of maintenance tasks. You can also monitor the amount of system resources your sites are using in real time and all of this data will inform you whether you should have an upgrade while you expand your world-wide web presence. When needed, you will be able to even reset the whole VPS to its original software installation.
