Virtuozzo Containers is a popular virtualization platform, which is used to generate virtual servers on physical machines. Each VPS created with it is a separate software emulation of a hosting server, so it has its own Operating System. The system resources are also fixed, therefore if you purchase a VPS plan with certain CPU, disk space and RAM quotas, they'll always be available and will not be shared with another client on the physical server. The Virtuozzo Containers software is truly intuitive and user-friendly, so even if you don't have much experience, you'll be able to manage the entire server using a web-based graphical interface. With just a couple of clicks, you can easily start/stop/reboot the virtual machine, set firewall rules, install server-side software packages and perform a number of maintenance tasks. You can also watch what amount of system resources your sites are using in real time and all this info can inform you if you'll need an upgrade as you expand your online presence. If needed, you'll be able to even reset the entire VPS to its original software configuration.
