Virtuozzo Containers is a widely used virtualization platform, that is used to generate virtual servers on physical machines. Every VPS created with it is a standalone software emulation of a website hosting server, which means that it has its own Operating System. The system resources are also preset, therefore if you get a VPS plan with certain disk space, CPU and RAM quotas, they are always available to you and will not be shared with another customer on the physical server. The Virtuozzo Containers software is really intuitive and convenient to use, so even if you do not have a lot of experience, you'll be able to control the whole server through a web-based graphical interface. With just a few clicks, you can easily start/stop/reboot the virtual machine, set firewall rules, install server-side software packages and do various maintenance tasks. You may also keep track of how much resources your web sites are using in real time and all of this data can show you if you will need an upgrade while you expand your web presence. If needed, you are able to even reset the whole VPS to its original software configuration.
