Virtuozzo Containers is a well-liked virtualization platform, that's used to set up virtual servers on physical machines. Each VPS made with it is an independent software emulation of a website hosting server, therefore it has its own OS. The resources are also predefined, which means that if you purchase a VPS package with certain CPU, disk space and RAM allocations, they're always available and will not be shared with another user on the physical server. The Virtuozzo Containers software is exceptionally intuitive and convenient to use, so even if you do not have a lot of experience, you can manage the whole server with a web-based graphical interface. With a few clicks, you can start/stop/reboot the virtual machine, manage firewall rules, install server-side software programs and do plenty of maintenance tasks. You can also monitor the amount of system resources your sites are using in real time and all of this data can show you whether you will need an upgrade while you expand your web presence. If needed, you will be able to even reset the entire VPS to its original software configuration.
