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.

Summary

Now, we understand in detail why we should monitor our microservices to make them production ready. We have done a deep dive into alerts to understand how we can define them correctly. Then, we have learned how we can use SpringBoot Actuator and how we can customize it. Finally, we learned what JMX actually is and how we can create management beans to allow us to operate our microservices.

Now that we have our microservice ready to reach production, we will need to learn how we can deploy it. In the next chapter, we will learn how we can deploy our microservices in a production system. We will use OpenShift online to create a cloud application and learn how we can set up a Git repository to automatically deploy our microservices, whenever they change.
