Virtuozzo Containers is a popular virtualization platform, that is used to make virtual servers on physical machines. Each VPS created with it is an independent software emulation of a website hosting server, therefore it has its own OS. The resources are also preset, which means that when you order a VPS package with certain CPU, RAM and disk space quotas, they are always available to you and won't be shared with another customer on the physical server. The Virtuozzo Containers software is particularly intuitive and convenient to use, so even if you don't have much experience, you will be able to control the entire server using a web-based graphical interface. With just a few clicks, you'll be able to start/stop/reboot your virtual machine, manage firewall rules, set up server-side software packages and perform various maintenance tasks. You may also watch what amount of resources your Internet sites use live and all this info can tell you if you will need upgrading as you expand your online presence. If needed, you're able to even reset the whole VPS to its original software setup.
