In this chapter, you learned about microservices and their architecture. You also understood the benefits we can enjoy while using microservice architecture and also the tradeoffs of those benefits. In the upcoming chapter, we will define a sample project risk-assessing system that will have microservice architecture. This system will evolve with each chapter of the book. The risk-calculating project will use Spring Boot and Docker for development and deployment. Both these technologies were introduced in this chapter. What's next? The next chapter will explain defining microservices and the discovery of the service. Also, we will define our first microservice of user registration with Spring Boot.
