Preface

The latest release of OpenStack, code-named Icehouse, was released in April 2014 and includes the networking service known as Neutron (formerly Quantum). First introduced in the Folsom release of OpenStack, Neutron provides cloud operators and users with an API to create and manage networks in the cloud. An extension framework allows for additional network services, such as load balancing, firewalls, and virtual private networks, to be deployed and managed.

It is important to note that OpenStack Networking in this book refers only to Neutron and should not be confused with the legacy networking service known as nova-network built in Nova (Compute). While nova-network has slipped its deprecation date in the last two releases, support for the technology is limited in the future.
