Virtuozzo Containers is a popular virtualization platform, which is used to generate virtual servers on physical machines. Each VPS made with it is an independent software emulation of a server, therefore it has its own OS. The system resources are also fixed, therefore if you order a VPS package with certain disk space, CPU and RAM allocations, they are always available and won't be shared with any other user on the physical server. The Virtuozzo Containers software is really intuitive and easy to use, so even if you do not have a lot of experience, you can control your entire server through a web-based graphical interface. With just a few clicks, you will be able to start/stop/reboot your virtual machine, set firewall rules, install server-side software and do numerous maintenance tasks. You can also watch the amount of system resources your web sites use in real time and this information will show you whether you will need an upgrade while you expand your online presence. When needed, you are able to even reset the entire VPS to its original software installation.
