Every project will have at least one network to launch instances on, which will be built as we have just built a network. Whenever a new project is created, the steps that have just been performed will need to be performed for that new project. All projects will share a network that provides external access to the outside world. Let's work through creating this external network.
Earlier, we discussed how Neutron is an API layer that manages virtual networking resources. The preparation for external network access will be different for different Neutron plugins. Talk to your networking vendor for your specific implementation.
