Virtuozzo Containers is a widely used virtualization platform, that is used to create virtual servers on physical machines. Every VPS created with it is an independent software emulation of a server, which means that it has its own Operating System. The system resources are also fixed, so if you purchase a VPS plan with certain disk space, CPU and RAM allocations, they're always readily available and won't be shared with another user on the physical server. The Virtuozzo Containers software is exceptionally intuitive and easy to use, so even if you don't have much experience, you will be able to control the whole server with a web-based graphical interface. With a few clicks, you can start/stop/reboot the virtual machine, manage firewall rules, set up server-side software and do plenty of maintenance tasks. You may also watch what amount of system resources your web sites use in real time and all of this information can show you if you need upgrading when you expand your online presence. If needed, you will be able to even reset the whole VPS to its original software installation.
