Virtuozzo Containers is a widely used virtualization platform, that is used to generate virtual servers on physical machines. Each VPS made with it is a separate software emulation of a server, so it has its own OS. The resources are also predefined, so when you get a VPS plan with certain disk space, RAM and CPU allocations, they are always available to you and won't be shared with some other client on the physical server. The Virtuozzo Containers software is really intuitive and user-friendly, so even if you do not have a lot of experience, you'll be able to manage your entire server using a web-based graphical interface. With a few clicks, you can easily start/stop/reboot your virtual machine, manage firewall rules, install server-side software programs and do a number of maintenance tasks. You may also track the amount of system resources your web sites are using in real time and this information will show you if you'll need upgrading as you expand your world-wide web presence. If needed, you'll be able to even reset the whole VPS to its original software configuration.
