Summary

In this chapter, we looked at the new federation capabilities in Kubernetes. We saw how we can deploy clusters to multiple cloud providers and manage them from a single control plane. We also deployed an application across clusters in both AWS and GCE. While these features are new and still mainly in alpha and beta, we should now have the skills to utilize them as they evolve and become part of the standard Kubernetes operating model. 

In the next chapter, we will take a look at another advanced topic: security. We will cover the basics for secure containers and also how to secure your Kubernetes cluster. We will also look at the Secrets construct, which gives us the capability to store sensitive configuration data similar to our preceding ConfigMap example.
