Virtuozzo Containers is a popular virtualization platform, which is used to make virtual servers on physical machines. Each VPS created with it is a separate software emulation of a hosting server, so it has its own OS. The resources are also fixed, thus when you acquire a VPS plan with certain CPU, RAM and disk space allocations, they're always available and won't be shared with another user on the server. The Virtuozzo Containers software is really intuitive and user-friendly, so even if you don't have much experience, you will be able to manage the whole 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, install server-side software applications and perform numerous maintenance tasks. You can also watch how much resources your websites use live and all of this information will show you whether you will need an upgrade when you expand your world-wide web presence. When needed, you can even reset the whole VPS to its original software installation.
