Virtuozzo Containers is a widely used virtualization platform, which is used to generate virtual servers on physical machines. Each VPS created with it is a standalone software emulation of a hosting server, therefore it has its own OS. The system resources are also preset, therefore if you obtain a VPS plan with certain disk space, RAM and CPU allocations, they'll always be at your disposal and won't be shared with some other user on the server. The Virtuozzo Containers software is truly intuitive and easy to use, so even if you don't have much experience, you will be able to control the whole server through a web-based graphical interface. With a few clicks, you can easily start/stop/reboot the virtual machine, set firewall rules, install server-side software and do plenty of maintenance tasks. You may also keep track of what amount of system resources your web sites use in real time and all of this information will inform you if you'll need upgrading as you expand your online presence. When needed, you are able to even reset the whole VPS to its original software installation.
