Virtuozzo Containers is a widely used virtualization platform, that's used to create virtual servers on physical machines. Every VPS created with it is a separate software emulation of a hosting server, therefore it has its own OS. The system resources are also fixed, thus when 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 really intuitive and user-friendly, so even if you don't have a lot of experience, you can control your entire server through a web-based graphical interface. With just a few clicks, you will be able to start/stop/reboot your virtual machine, set firewall rules, install server-side software packages and perform plenty of maintenance tasks. You can also keep track of what amount of system resources your websites use in real time and all this data can tell you whether you should have an upgrade when you expand your web presence. When needed, you will be able to even reset the entire VPS to its original software installation.
