Overview of this book

Well-written software architecture is the core of an efficient and scalable enterprise application. Java, the most widespread technology in current enterprises, provides complete toolkits to support the implementation of a well-designed architecture. This book starts with the fundamentals of architecture and takes you through the basic components of application architecture. You'll cover the different types of software architectural patterns and application integration patterns and learn about their most widespread implementation in Java. You'll then explore cloud-native architectures and best practices for enhancing existing applications to better suit a cloud-enabled world. Later, the book highlights some cross-cutting concerns and the importance of monitoring and tracing for planning the evolution of the software, foreseeing predictable maintenance, and troubleshooting. The book concludes with an analysis of the current status of software architectures in Java programming and offers insights into transforming your architecture to reduce technical debt. By the end of this software architecture book, you'll have acquired some of the most valuable and in-demand software architect skills to progress in your career.

Adopting microservices and evolving existing applications

So, we had an overview of the benefits of microservices applications and some of their particular characteristics. I think it is now relevant to better consider why you should (or should not) adopt this architectural style. This kind of consideration can be useful both for the creation of new applications from scratch (in what is called green-field development) and modernization (termed brown-field applications). Regarding the latter aspect, we will discuss some of the suggested approaches for modernizing existing applications in the upcoming sections.

But back to our main topic for this section: why should you adopt the microservices-based approach?

The first and most important reason for creating microservices is the release frequency. Indeed, the most famous and successful production experiences of microservices applications are related to services heavily benefitting from being released often.

This is because a...
