In the first part of this chapter, we discussed the key principles behind RESTful APIs. We focused on effective strategies for handling hot topics such as security and versioning. Then, we analyzed the pros and cons of RESTful APIs compared to the RPC-base paradigm used by the gRPC framework and highlighted the key differences that make gRPC more suitable for building high-performance services.
Now that you're at the end of this chapter, you should be familiar with the protocol buffer definition language and know how to leverage the various features supported by the gRPC framework for building high-performance secure APIs based on the RPC pattern.
In the next chapter, we will find out how we can perform hermetic builds of our software, package it as a container image, and deploy it on a Kubernetes cluster.
