Reactive microservice performs operations in response to events. We'll make changes in our code to produce and consume events for our sample implementation. Although we'll create a single event, a microservice can have multiple producers or consumer events. Also, a microservice can have both producer and consumer events. We'll make use of the existing functionality in the Booking microservice that creates the new booking (POST /v1/booking). This will be our event source and would make use of Apache Kafka for sending this event. Other microservices can consume this event by listening to the event. On successful booking call, the Booking microservice will produce the Kafka topic (event) amp.bookingOrdered. We'll create a new microservice Billing (in the same way in which we created the other microservices like Booking) for...

Overview of this book
Microservices are the next big thing in designing scalable, easy-to-maintain applications. They not only make app development easier, but also offer great flexibility to utilize various resources optimally. If you want to build an enterprise-ready implementation of the microservices architecture, then this is the book for you!
Starting off by understanding the core concepts and framework, you will then focus on the high-level design of large software projects. You will gradually move on to setting up the development environment and configuring it before implementing continuous integration to deploy your microservice architecture. Using Spring security, you will secure microservices and test them effectively using REST Java clients and other tools like RxJava 2.0. We'll show you the best patterns, practices and common principles of microservice design and you'll learn to troubleshoot and debug the issues faced during development. We'll show you how to design and implement reactive microservices. Finally, we’ll show you how to migrate a monolithic application to microservices based application.
By the end of the book, you will know how to build smaller, lighter, and faster services that can be implemented easily in a production environment.
