Virtuozzo Containers is a widespread virtualization platform, that's used to set up virtual servers on physical machines. Every VPS created with it is a separate software emulation of a website hosting server, so it has its own Operating System. The system resources are also fixed, thus if you get a VPS plan with certain CPU, RAM and disk space allocations, they'll always be available and won't be shared with any other client on the physical server. The Virtuozzo Containers software is truly intuitive and user-friendly, so even if you do not have much experience, you can control the entire server using a web-based graphical interface. With a couple of clicks, you'll be able to start/stop/reboot your virtual machine, set firewall rules, set up server-side software packages and do a variety of maintenance tasks. You may also watch how much system resources your sites use live and all of this data will tell you if you'll need upgrading as you expand your online presence. When needed, you will be able to even reset the entire VPS to its original software installation.
