Summary
As seen in this chapter, OpenStack supports a wide variety of networking functionality right out of the box. The importance of isolating tenant traffic and the need to allow customized solutions requires OpenStack to support flexible configuration. We also highlighted some key aspects of OpenStack that will play a key role in deploying SDN in data centers, thereby supporting powerful cloud architecture and solutions.
The following chapter will introduce SDN and demonstrate how it solves some of the challenges with traditional networking. We will examine how OpenStack and SDN together provide a modern cloud networking solution.
