Virtuozzo Containers is a widespread virtualization platform, that's used to make virtual servers on physical machines. Every VPS made with it is an independent software emulation of a website hosting server, so it has its own OS. The resources are also predefined, thus when you buy a VPS plan with certain CPU, RAM and disk space allocations, they will always be readily available and will not be shared with another user on the server. The Virtuozzo Containers software is particularly intuitive and convenient to use, so even if you don't have a lot of experience, you can manage the whole server with a web-based graphical interface. With only a few clicks, you can start/stop/reboot the virtual machine, manage firewall rules, set up server-side software programs and do many different maintenance tasks. You may also track the amount of system resources your websites use in real time and all of this information can tell you whether you'll need an upgrade while you expand your web presence. When needed, you're able to even reset the whole VPS to its original software setup.
