Virtuozzo Containers is a widely used virtualization platform, that's used to make virtual servers on physical machines. Each VPS made with it is an independent software emulation of a server, so it has its own Operating System. The system resources are also fixed, so when you acquire a VPS plan with certain CPU, disk space and RAM quotas, they're always at your disposal and won't be shared with some other customer on the physical server. The Virtuozzo Containers software is really intuitive and user-friendly, so even if you do not have much experience, you will be able to manage the whole server using 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 programs and do a variety of maintenance tasks. You may also keep track of the amount of system resources your websites are using in real time and all of this info will inform you if you need upgrading while you expand your world-wide web presence. If needed, you'll be able to even reset the whole VPS to its original software setup.
