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.

Case studies and examples

In this section, we are going to go on with our payment use case, to see some examples of integration and business automation.

For example purposes, we will use Camel, jBPM, and Drools. Our target runtime will be Quarkus, which we already saw in the previous chapter.

But many of the concepts and implementations are applicable to other runtimes, such as embedded ones (as in using the runtime as a dependency of your Java application), deployed on JBoss WildFly, and deployed on Spring Boot.

Integrating payment capabilities

Our first use case to implement integration is the connection of payment capabilities with a legacy backend. Let's suppose that we have developed our microservices payment application and it is working correctly. A new business requirement is to integrate a legacy platform for settlement purposes (which is a kind of accounting operation done after payments).

It's fairly easy for our core application to call a REST service...
