Virtuozzo Containers is a popular virtualization platform, that is used to generate virtual servers on physical machines. Every VPS made with it is an independent software emulation of a server, therefore it has its own OS. The resources are also fixed, which means that when you purchase a VPS package with certain CPU, RAM and disk space allocations, they will always be available and won't be shared with another user on the server. The Virtuozzo Containers software is truly intuitive and user-friendly, so even if you do not have much experience, you'll be able to control the entire server with a web-based graphical interface. With a few clicks, you can start/stop/reboot your virtual machine, set firewall rules, install server-side software applications and do a number of maintenance tasks. You can also keep track of what amount of resources your sites are using in real time and all of this information can show you whether you need upgrading when you expand your online presence. When needed, you're able to even reset the entire VPS to its original software setup.
