Virtuozzo Containers is a popular virtualization platform, that is used to make virtual servers on physical machines. Each VPS made with it is a standalone software emulation of a website hosting server, which means that it has its own OS. The resources are also fixed, so if you order a VPS package with certain CPU, disk space and RAM quotas, they will always be at your disposal and won't be shared with another client on the server. The Virtuozzo Containers software is really intuitive and user-friendly, so even if you don't have a lot of experience, you will be able to control your entire server with a web-based graphical interface. With a few clicks, you can start/stop/reboot your virtual machine, set firewall rules, install server-side software programs and perform a variety of maintenance tasks. You can also keep track of the amount of resources your sites are using in real time and all this information can show you whether you should have an upgrade as you expand your world-wide web presence. If needed, you can even reset the whole VPS to its original software setup.
