In this chapter, we have learned about OKD, the community project on which OpenShift is based.

We also described and learned how an application can be internally called by its service name, and how an application is reachable from outside the platform by relying on the Route component.

In the next chapter, we will describe the common patterns used when designing and building microservices using containers; more specifically, using OpenShift as PaaS. We will also implement and test the efficiency of those patterns with real-time examples.
