Virtuozzo Containers is a popular virtualization platform, that is used to set up virtual servers on physical machines. Every VPS made with it is a separate software emulation of a server, therefore it has its own OS. The system resources are also fixed, which means that if you obtain a VPS plan with certain CPU, disk space and RAM allocations, they'll always be available and won't be shared with another customer on the server. The Virtuozzo Containers software is really intuitive and easy to use, so even if you don't have a lot of experience, you can manage your entire server with a web-based graphical interface. With just a couple of clicks, you will be able to start/stop/reboot the virtual machine, set firewall rules, set up server-side software applications and perform numerous maintenance tasks. You may also watch the amount of system resources your websites use live and this info will tell you if you'll need upgrading as you expand your online presence. If needed, you'll be able to even reset the whole VPS to its original software installation.
