What's Next?

Review what we’ve learned so far in this chapter and what we’ll learn next.

Everything we learned led us to Deployments. Pods must not be created directly, but through ReplicaSets which, similarly, must not be created directly, but through Deployments. They are the objects that allow us not only to create the ReplicaSets and Pods, but that can also be updated without producing any downtime (when applications are designed accordingly).

We combine Deployments with Services so that Pods can communicate with each other and be accessed from outside a cluster. All in all, we have everything we need to release our Services to production. That is not to say that we understand all the crucial aspects of Kubernetes. We’re not even close to that point. However, we do have almost everything we need to run some types of applications in production. What we’re missing now is just networking.
