Virtuozzo Containers is a widespread virtualization platform, which is used to generate virtual servers on physical machines. Each VPS created with it is a standalone software emulation of a website hosting server, so it has its own OS. The resources are also predefined, thus if you obtain a VPS plan with certain CPU, RAM and disk space quotas, they will always be available and will not be shared with any other user on the server. The Virtuozzo Containers software is really intuitive and convenient to use, so even if you do not have much experience, you'll be able to control the whole server through a web-based graphical interface. With only a few clicks, you can start/stop/reboot the virtual machine, set firewall rules, install server-side software packages and do numerous maintenance tasks. You can also monitor how much system resources your websites are using live and all this data will show you whether you should have an upgrade when you expand your world-wide web presence. If needed, you'll be able to even reset the entire VPS to its original software installation.
