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.

Deploying Microservices

To have our microservices ready in our production environments, we need to deploy them, and this task may look trivial, but it can become an impediment to delivering the pace and speed required by our application. In this chapter, we will be using OpenShift Online to understand how we can easily and effectively deploy microservices, and how this can be done in such a way that allows us to deliver the best quality at the best speed. To help us in this task, we will be using Git, the industry standard control version system, to simplify our deployments.

In this chapter, you will learn about:

  • OpenShift Online
  • Git
  • GitHub
  • Deployments
  • Webhooks
