Virtuozzo Containers is a widely used virtualization platform, which is used to generate virtual servers on physical machines. Every VPS made with it is a standalone software emulation of a server, which means that it has its own OS. The resources are also predefined, thus if you order a VPS plan with certain CPU, disk space and RAM allocations, they will always be readily available and will not be shared with any other client on the physical server. The Virtuozzo Containers software is particularly intuitive and user-friendly, so even if you don't have a lot of experience, you will be able to control the entire server with a web-based graphical interface. With just a few clicks, you will be able to start/stop/reboot the virtual machine, manage firewall rules, set up server-side software and perform various maintenance tasks. You can also monitor what amount of system resources your web sites use in real time and all of this data can show you if you will need an upgrade when you expand your world-wide web presence. When needed, you'll be able to even reset the whole VPS to its original software installation.
