Virtuozzo Containers is a widely used virtualization platform, that's used to create virtual servers on physical machines. Every VPS created with it is an independent software emulation of a website hosting server, which means that it has its own OS. The system resources are also fixed, which means that if you acquire a VPS plan with certain disk space, RAM and CPU quotas, they are always at your disposal and will not be shared with some other user on the physical server. The Virtuozzo Containers software is really intuitive and convenient to use, so even if you do not have much experience, you will be able to manage the entire server with a web-based graphical interface. With just a couple of clicks, you can start/stop/reboot the virtual machine, set firewall rules, set up server-side software and do a range of maintenance tasks. You can also watch the amount of system resources your web sites are using in real time and all this info can tell you if you should have upgrading while you expand your world-wide web presence. When needed, you're able to even reset the whole VPS to its original software setup.
