Virtuozzo Containers is a widely used virtualization platform, that is used to generate virtual servers on physical machines. Each VPS created with it is an independent software emulation of a website hosting server, so it has its own Operating System. The system resources are also predefined, which means that if you order a VPS package with certain CPU, disk space and RAM allocations, they are always available to you and won't be shared with another user on the physical server. The Virtuozzo Containers software is truly intuitive and convenient to use, so even if you do not have a lot of experience, you will be able to control the whole server through a web-based graphical interface. With only a few clicks, you'll be able to start/stop/reboot the virtual machine, set firewall rules, set up server-side software and do plenty of maintenance tasks. You may also monitor what amount of resources your websites use in real time and all this info will show you whether you will need an upgrade while you expand your online presence. When needed, you can even reset the whole VPS to its original software setup.
