Neutron enables users to build routers that provide connectivity between the networks created by users and external networks. In a reference implementation, the Neutron L3 agent provides IP routing and network address translation for virtual machine instances within a cloud by utilizing network namespaces to provide isolated routing instances. By creating networks and attaching them to routers, users can expose connected virtual machine instances and their applications to the Internet and other remote networks.
