This chapter laid a foundation for creating networks and subnets that can be utilized by instances and other virtual and physical network devices. Both the Horizon dashboard and the Neutron command-line client can be used to manage networks, subnets, and ports, though the latter is recommended for most administrative tasks.

For more information on network, subnet, and port attributes as well as for guidance on how to use the Neutron API, refer to the OpenStack Wikipedia page at https://wiki.openstack.org/wiki/Neutron/APIv2-specification.

For additional details on deployment scenarios based on provider networks, refer to OpenStack Networking Guide available at http://docs.openstack.org/networking-guide/.

In the next chapter, you will learn how to leverage the Neutron security group functionality to provide network-level security to instances. The configuration of virtual firewalls can be found in Chapter 11, Firewall as a Service.
