Virtuozzo Containers is a widely used virtualization platform, that is used to make virtual servers on physical machines. Each VPS made with it is a separate software emulation of a website hosting server, which means that it has its own Operating System. The system resources are also preset, thus when you purchase a VPS package with certain disk space, RAM and CPU allocations, they are always available to you and will not be shared with some other user on the physical server. The Virtuozzo Containers software is particularly intuitive and user-friendly, 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 will be able to start/stop/reboot the virtual machine, manage firewall rules, set up server-side software programs and do various maintenance tasks. You can also keep track of what amount of system resources your sites use in real time and all this information will inform you if you should have an upgrade as you expand your web presence. If needed, you are able to even reset the entire VPS to its original software configuration.
