Virtuozzo Containers is a widespread virtualization platform, that is used to set up virtual servers on physical machines. Each VPS made with it is a standalone software emulation of a hosting server, so it has its own OS. The resources are also predefined, therefore if you acquire a VPS package with certain disk space, RAM and CPU quotas, they are always available to you and will not be shared with any other user on the physical server. The Virtuozzo Containers software is really intuitive and easy to use, so even if you don't have a lot of experience, you will be able to manage the entire server with a web-based graphical interface. With only a couple of clicks, you can start/stop/reboot the virtual machine, set firewall rules, install server-side software and do numerous maintenance tasks. You can also watch how much system resources your web sites are using in real time and all of this information will tell you if you will need upgrading as you expand your online presence. If needed, you are able to even reset the entire VPS to its original software configuration.
