Overview of this book

Spring 5.0 is due to arrive with a myriad of new and exciting features that will change the way we’ve used the framework so far. This book will show you this evolution—from solving the problems of testable applications to building distributed applications on the cloud. The book begins with an insight into the new features in Spring 5.0 and shows you how to build an application using Spring MVC. You will realize how application architectures have evolved from monoliths to those built around microservices. You will then get a thorough understanding of how to build and extend microservices using Spring Boot. You will also understand how to build and deploy Cloud-Native microservices with Spring Cloud. The advanced features of Spring Boot will be illustrated through powerful examples. We will be introduced to a JVM language that’s quickly gaining popularity - Kotlin. Also, we will discuss how to set up a Kotlin project in Eclipse. By the end of the book, you will be equipped with the knowledge and best practices required to develop microservices with the Spring Framework.

Preface

Challenges with monolithic applications


Over the last few years, in parallel to working with several small applications, I had the opportunity to work on four different monolithic applications in varied domains--insurance, banking, and health care. All these applications had very similar challenges. In this section, we will start with looking at the characteristics of monoliths and then look at the challenges they bring in.

First of all: What is a monolith? An application with a lot of code--may be greater than 100K lines of code? Yeah.

For me, monoliths are those applications for which getting a release out to production is a big challenge. Applications that fall into this category have a number of user requirements that are immediately needed, but these applications are able to do new feature releases once every few months. Some of these applications even do feature releases once a quarter or sometimes even as less as twice a year.

Typically, all monolithic applications have these characteristics...
