Book Description: In this third edition of "Learn Microservices with Spring Boot," we explore the practical approach of using event-driven architecture to build scalable and resilient microservices systems. The book covers the latest features of Spring Boot 3, including the new reactive web framework, WebFlux, and the improvements in the area of security, testing, and deployment. We will delve into the world of microservices and learn how to create them from scratch, focusing on the development of real-world applications. The book begins by introducing the concept of microservices and their importance in today's technology landscape. We will discuss the evolution of technology and how it has led to the creation of microservices, which are essential for building scalable and resilient systems. We will also cover the benefits of using microservices, such as increased flexibility, faster development cycles, and better maintainability. Next, we will dive into the details of Spring Boot 3, exploring its features and capabilities, and how they can be used to build robust and scalable microservices. We will focus on the reactive web framework, WebFlux, and its ability to handle high traffic and large volumes of data. We will also discuss the improvements in security, testing, and deployment, and how they contribute to a more secure and reliable system. As we progress through the book, we will explore the practical aspects of event-driven architecture, including the use of events to drive the flow of a system. We will discuss the different types of events and how they can be used to communicate between services, and the importance of proper event handling and routing.
