With Google's announcement of introducing first-class support for Kotlin in their Android ecosystem, Kotlin is realized as a mainstream language.

Microservices helps with designing scalable, easy-to-maintain web applications, and Kotlin allows us to take advantage of modern idioms to simplify our development and create high-quality services.

With 100% of interoperability with the JVM, Kotlin makes it easy to work with the existing Java code.

Popular Java frameworks, such as Spring, Jackson, and Reactor, have included Kotlin modules to take advantage of language features such as null safety and type-safe declarative builders.

This book will guide the reader through designing and implementing services to having the production-ready testable code, creating easy-to-maintain and lean code that will be shorter and simpler than a traditional Java implementation.

We will discover the benefits of using the reactive paradigm in order to take advantage of non-blocking techniques and take our services to the next level of industry standards.

During the journey, we'll consume NoSQL databases reactively in order to create high- throughput microservices.

In this book, we will demonstrate how we can create Cloud-Native microservices that can run in a wide range of cloud providers, and how we can monitor them.

We will create Docker containers for our microservices and learn how to scale them.

Finally, we will deploy our microservices in Openshift Online.
