Virtuozzo Containers is a popular virtualization platform, that's used to make virtual servers on physical machines. Each VPS created with it is a separate software emulation of a server, so it has its own OS. The system resources are also fixed, so when you acquire a VPS plan with certain disk space, CPU and RAM allocations, they're always available to you and won't be shared with any other user on the server. The Virtuozzo Containers software is particularly intuitive and convenient to use, so even if you do not have a lot of experience, you'll be able to control the entire server through a web-based graphical interface. With only a few clicks, you'll be able to start/stop/reboot your virtual machine, set firewall rules, set up server-side software programs and perform a number of maintenance tasks. You can also monitor how much resources your websites use in real time and all of this info can tell you whether you need upgrading as you expand your world-wide web presence. When needed, you're able to even reset the entire VPS to its original software configuration.
