Virtuozzo Containers is a widely used virtualization platform, that is used to make virtual servers on physical machines. Every VPS made with it is a standalone software emulation of a website hosting server, so it has its own OS. The system resources are also fixed, therefore if you get a VPS plan with certain disk space, CPU and RAM quotas, they are always available and will not be shared with some other user on the physical server. The Virtuozzo Containers software is exceptionally intuitive and user-friendly, so even if you don't have a lot of experience, you will be able to manage your entire server using 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 packages and do various maintenance tasks. You may also watch the amount of resources your sites are using live and all of this information can tell you whether you'll need an upgrade as you expand your online presence. If needed, you will be able to even reset the whole VPS to its original software setup.
