Mastering Microservices with Java 9 - Second Edition

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.

Summary

In this chapter, we have learned about various microservice management features: load balancing, edge (gateway) servers, circuit breakers, and monitoring. You should now know how to implement load balancing and routing after going through this chapter. We have also learned how edge servers can be set up and configured. The failsafe mechanism is another important part that you have learned in this chapter. Deployment can be made simple by using Docker or any other container. Docker was demonstrated and integrated using Maven Build.

From a testing point of view, we performed the integration testing on the Docker image of the service. We also explored the way we can write clients such as RestTemplate and Netflix Feign.

In the next chapter, we will learn to secure the microservices with respect to authentication and authorization. We will also explore the other aspects of...
