Hands-On Microservices with Kotlin

By: Juan Antonio Medina Iglesias

Overview of this book

With Google's inclusion of first-class support for Kotlin in their Android ecosystem, Kotlin's future as a mainstream language is assured. Microservices help design scalable, easy-to-maintain web applications; Kotlin allows us to take advantage of modern idioms to simplify our development and create high-quality services. With 100% interoperability with the JVM, Kotlin makes working with existing Java code easier. Well-known Java systems such as Spring, Jackson, and Reactor have included Kotlin modules to exploit its language features. This book guides the reader in designing and implementing services, and producing production-ready, testable, lean code that's shorter and simpler than a traditional Java implementation. Reap the benefits of using the reactive paradigm and take advantage of non-blocking techniques to take your services to the next level in terms of industry standards. You will consume NoSQL databases reactively to allow you to create high-throughput microservices. Create cloud-native microservices that can run on a wide range of cloud providers, and monitor them. You will create Docker containers for your microservices and scale them. Finally, you will deploy your microservices in OpenShift Online.

Understanding Microservices

Microservices and their continuously evolving architecture have become one of the most used approaches in enterprise applications. In this book, we will try to get an understanding of what they really are and the principles that they are based on. Using Domain-Driven Design, we will reinforce those principles to maintain a clean architecture that can evolve with our applications.

Since microservices have no static architecture, we will discover how the new reactive paradigm could change the way we create them. And, finally, we will have an overview of cloud architecture and why we should create Cloud Native microservices.

In this chapter, you will learn about:

  • What a microservice really is
  • Understanding microservices principles
  • Using Domain-Driven Design for a clean architecture
  • Non-blocking reactive microservices
  • Cloud Native microservices and their benefits
