Kotlin for Enterprise Applications using Java EE

By: Raghavendra Rao K

Overview of this book

Kotlin was developed with a view to solving programmers’ difficulties and operational challenges. This book guides you in making Kotlin and Java EE work in unison to build enterprise-grade applications. Together, they can be used to create services of any size with just a few lines of code and let you focus on the business logic. Kotlin for Enterprise Applications using Java EE begins with a brief tour of Kotlin and helps you understand what makes it a popular and reasonable choice of programming language for application development, followed by its incorporation in the Java EE platform. We will then learn how to build applications using the Java Persistence API (JPA) and Enterprise JavaBeans (EJB), as well as develop RESTful web services and MicroServices. As we work our way through the chapters, we’ll use various performance improvement and monitoring tools for your application and see how they optimize real-world applications. At each step along the way, we will see how easy it is to develop enterprise applications in Kotlin. By the end of this book, we will have learned design patterns and how to implement them using Kotlin.

Implementing Microservices with Kotlin

In the modern, cloud-based application era, the idea of a monolith application that manages all tasks no longer exists. The application is designed in small pieces, each handling a single business responsibility. Microservices is an architectural style in which a large complex application is composed of multiple, smaller services:

This style loosely couples the system being developed and each service can be developed independently. With Kotlin, it is much easier to write the microservices in order to experience the benefits of this architectural style of developing software.

In this chapter, we will discuss the following:

  • Microservices and their architecture
  • Breaking a monolith application into smaller microservices
  • The benefits of the microservices architecture style
  • How to test microservices
