Virtuozzo Containers is a widely used virtualization platform, that's used to make virtual servers on physical machines. Every VPS created with it is a separate software emulation of a server, therefore it has its own Operating System. The system resources are also predefined, which means that when you order a VPS package with certain disk space, CPU and RAM quotas, they are always available and will not be shared with some other user on the server. The Virtuozzo Containers software is particularly intuitive and user-friendly, so even if you do not have much experience, you can manage your entire server with a web-based graphical interface. With only a couple of clicks, you can start/stop/reboot the virtual machine, set firewall rules, set up server-side software applications and do plenty of maintenance tasks. You can also watch what amount of system resources your websites are using live and this data will show you if you'll need an upgrade when you expand your online presence. If needed, you're able to even reset the whole VPS to its original software installation.
