In this chapter, we walked through the north-south infrastructure of CNAs, which require a toolchain. Then, we walked through their key essential attributes. We looked at the different container runtimes that are available, which form the basis of cloud computing. Then, we delved into the container orchestration platform. We highlighted that Kubernetes is the de facto standard and that we'll be using it in this book. Lastly, we looked at the major cloud-native infrastructures that are available so that we can deploy CNAs. 

In the next chapter, we will cover the service mesh architecture, service mesh providers, the service mesh interface, and the Secure Production Identity Framework For Everyone (SPIFFE). We will also look at the data plane that builds the service mesh with components that are driven through the control plane.
