Virtuozzo Containers is a popular virtualization platform, that is used to make virtual servers on physical machines. Every VPS made with it is a standalone software emulation of a hosting server, so it has its own OS. The system resources are also fixed, which means that if you obtain a VPS plan with certain CPU, disk space and RAM quotas, they are always readily available and won't be shared with another user on the physical server. The Virtuozzo Containers software is very intuitive and easy to use, so even if you do not have a lot of experience, you can manage the entire server through a web-based graphical interface. With a few clicks, you'll be able to start/stop/reboot your virtual machine, manage firewall rules, install server-side software applications and do many different maintenance tasks. You can also keep track of the amount of system resources your Internet sites use in real time and all this information will inform you if you should have an upgrade when you expand your web presence. When needed, you'll be able to even reset the entire VPS to its original software setup.
