Virtuozzo Containers is a widely used virtualization platform, which is used to create 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, thus if you purchase a VPS package with certain CPU, disk space and RAM allocations, they are always at your disposal and will not be shared with some other user on the server. The Virtuozzo Containers software is very intuitive and convenient to use, so even if you don't have much experience, you will be able to manage your entire server with a web-based graphical interface. With a couple of clicks, you can easily start/stop/reboot the virtual machine, set firewall rules, set up server-side software programs and do numerous maintenance tasks. You may also keep track of what amount of resources your web sites use in real time and all of this information will tell you if you need upgrading when you expand your world-wide web presence. When needed, you can even reset the whole VPS to its original software installation.
