Virtuozzo Containers is a widely used virtualization platform, that's used to create virtual servers on physical machines. Each VPS made with it is a standalone software emulation of a server, so it has its own Operating System. The system resources are also fixed, therefore if you buy a VPS package with certain disk space, CPU and RAM allocations, they will always be readily available and won't be shared with some other user on the server. The Virtuozzo Containers software is very intuitive and easy to use, so even if you do not have much experience, you'll be able to control your entire server using a web-based graphical interface. With only a couple of clicks, you will be able to start/stop/reboot the virtual machine, manage firewall rules, set up server-side software and do a number of maintenance tasks. You may also track the amount of system resources your websites use live and all this information can inform you if you will need an upgrade as you expand your online presence. If needed, you're able to even reset the whole VPS to its original software setup.
