Virtuozzo Containers is a popular virtualization platform, which is used to create virtual servers on physical machines. Each VPS made with it is a standalone software emulation of a hosting server, so it has its own Operating System. The system resources are also preset, which means that if you obtain a VPS package with certain CPU, disk space and RAM quotas, they are always available and won't be shared with some other user on the physical server. The Virtuozzo Containers software is particularly intuitive and user-friendly, so even if you do not have a lot of experience, you will be able to manage the entire server through a web-based graphical interface. With a few clicks, you can start/stop/reboot your virtual machine, set firewall rules, set up server-side software programs and perform various maintenance tasks. You can also keep track of what amount of system resources your websites use in real time and all this data will show you whether you will need an upgrade when you expand your online presence. If needed, you will be able to even reset the whole VPS to its original software installation.
