We’ve come a long way, and you’re now in front of the second hands-on chapter of the book. It’s time again to put into action all you’ve learned in an exercise that shows you the big picture. Fasten your seat belts, open your IDEs, and get ready for an adventure!
In this chapter, we’ll design a system of three actors: the client, the authentication server, and the business logic server. From these three actors, we’ll implement the backend part of the authentication server and a business logic server. As you’ll observe, our examples are more complex. This is a sign that we are getting closer and closer to real-world scenarios.
