Virtuozzo Containers is a popular virtualization platform, that is used to set up virtual servers on physical machines. Every VPS made with it is a separate software emulation of a hosting server, therefore it has its own Operating System. The system resources are also fixed, so when you get a VPS plan with certain disk space, RAM and CPU quotas, they're always available to you and won't be shared with some other client on the server. The Virtuozzo Containers software is truly intuitive and easy to use, so even if you do not have much experience, you can control your entire server through a web-based graphical interface. With just a couple of clicks, you will be able to start/stop/reboot your virtual machine, manage firewall rules, install server-side software and do various maintenance tasks. You can also monitor what amount of system resources your websites use in real time and all of this info can inform you if you need upgrading when you expand your world-wide web presence. If needed, you will be able to even reset the whole VPS to its original software installation.
