In this chapter, you learned how to scale and discover services inside the cluster. As you were able to see throughout this chapter, most of the work was done by OpenShift. Load balancing is implemented automatically by the services, and the integrated DNS service allows for straightforward service discovery.
In the next chapter, you will learn more about networking. You will also learn how to provide resiliency to a service invocation so that underlying network failures won't cause your application to stop working.
