Build smart, efficient, and fast enterprise-grade web implementation of the microservices architecture that can be easily scaled.
Key Features • Write easy-to-maintain lean and clean code with Kotlin for developing better microservices
 • Scale your Microserivces in your own cloud with Docker and Docker Swarm
 • Explore Spring 5 functional reactive web programming with Spring WebFlux
Book Description
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.
What you will learn • Understand microservice architectures and principles
 • Build microservices in Kotlin using Spring Boot 2.0 and Spring Framework 5.0
 • Create reactive microservices that perform non-blocking operations with Spring WebFlux
 • Use Spring Data to get data reactively from MongoDB
 • Test effectively with JUnit and Kotlin
 • Create cloud-native microservices with Spring Cloud
 • Build and publish Docker images of your microservices
 • Scaling microservices with Docker Swarm
 • Monitor microservices with JMX
 • Deploy microservices in OpenShift Online
Who this book is for
If you are a Kotlin developer with a basic knowledge of microservice architectures and now want to effectively implement these services on enterprise-level web applications, then this book is for you
