Virtuozzo Containers is a widely used virtualization platform, that's used to generate virtual servers on physical machines. Every VPS made with it is a standalone software emulation of a website hosting server, therefore it has its own Operating System. The resources are also fixed, thus if you order a VPS package with certain CPU, disk space and RAM allocations, they will always be available and will not be shared with another user on the physical server. The Virtuozzo Containers software is particularly intuitive and convenient to use, so even if you don't have much experience, you'll be able to manage the entire server through a web-based graphical interface. With a couple of clicks, you'll be able to start/stop/reboot the virtual machine, manage firewall rules, install server-side software and do many different maintenance tasks. You can also watch what amount of system resources your websites use live and all of this data will show you if you should have upgrading while you expand your web presence. When needed, you will be able to even reset the whole VPS to its original software installation.
