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 resources are also fixed, so if you buy a VPS plan with certain CPU, disk space and RAM quotas, they are always readily available and won't be shared with another client on the physical server. The Virtuozzo Containers software is very intuitive and user-friendly, so even if you do not have much experience, you can manage the entire server using a web-based graphical interface. With just a few clicks, you'll be able to start/stop/reboot the virtual machine, manage firewall rules, install server-side software and do plenty of maintenance tasks. You can also keep track of the amount of system resources your web sites use live and this info will inform you if you will need an upgrade when you expand your online presence. If needed, you can even reset the entire VPS to its original software configuration.
