In this chapter, you learned about the importance of SDN and the role it plays in OpenShift, the composed network topology diagram for an existing OpenShift cluster, gained knowledge on various OpenShift and third-party plugins, and saw for yourself what features they provide. You also learned about use cases of both egress routers and static IPs for external project traffic, and also created your own egress network policy to restrict access to an external resource.
In the next chapter, we will be working on the deployment of a simple application.
