Virtuozzo Containers is a popular virtualization platform, that is used to create virtual servers on physical machines. Every VPS made with it is a separate software emulation of a server, which means that it has its own OS. The system resources are also predefined, so if you get a VPS plan with certain disk space, RAM and CPU allocations, they're always available and will not be shared with some other user on the physical server. The Virtuozzo Containers software is particularly intuitive and easy to use, so even if you do not have a lot of experience, you'll be able to control your entire server through a web-based graphical interface. With a couple of clicks, you will be able to start/stop/reboot the virtual machine, manage firewall rules, install server-side software applications and do numerous maintenance tasks. You may also watch what amount of system resources your Internet sites use live and all this data will show you if you should have an upgrade when you expand your web presence. If needed, you will be able to even reset the whole VPS to its original software setup.
