Architecting Modern Java EE Applications

By: Sebastian Daschner

Overview of this book

Java EE 8 brings with it a load of features, mainly targeting newer architectures such as microservices, modernized security APIs, and cloud deployments. This book will teach you to design and develop modern, business-oriented applications using Java EE 8. It shows how to structure systems and applications, and how design patterns and Domain Driven Design aspects are realized in the age of Java EE 8. You will learn about the concepts and principles behind Java EE applications, and how to effect communication, persistence, technical and cross-cutting concerns, and asynchronous behavior. This book covers Continuous Delivery, DevOps, infrastructure-as-code, containers, container orchestration technologies, such as Docker and Kubernetes, and why and especially how Java EE fits into this world. It also covers the requirements behind containerized, zero-dependency applications and how modern Java EE application servers support these approaches. You will also learn about automated, fast, and reliable software tests, in different test levels, scopes, and test technologies. This book covers the prerequisites and challenges of distributed systems that lead to microservice, shared-nothing architectures. The challenges and solutions of consistency versus scalability will further lead us to event sourcing, event-driven architectures, and the CQRS principle. This book also includes the nuts and bolts of application performance as well as how to realize resilience, logging, monitoring and tracing in a modern enterprise world. Last but not least the demands of securing enterprise systems are covered. By the end, you will understand the ins and outs of Java EE so that you can make critical design decisions that not only live up to, but also surpass your clients' expectations.

There are many people whom I had the privilege to meet during my career, and who had a great impact not only on my work but also this book and without whom this would not have been possible. This list of people grows and grows every year. All of them are indirectly helped shaping this book, which I immensely appreciate.

There are a few friends who had a direct impact on this book and whom I particularly want to thank.

Kirk Pepperdine, for his tireless aspiration to myth-bust the world of software performance and for the permission to use jPDM. His invaluable experience not only vastly improved the quality of this book but also greatly educated me personally.

Melissa McKay, for her tireless reviews, being eager (and crazy) enough to review this whole book, what greatly improved the quality, for sharing her experience in Enterprise Java, and not least for inspiration and motivation.

David Blevins, for sharing the passion in the topic of Java EE and writing the foreword to this book.

Andy Gumbrecht, for help not only in the topic of enterprise testing but also the English language.

Markus Eisele, for igniting the spark of this work.

Philipp Brunenberg, for creating constructive inspiration and not least, tons of motivation through weeks of writing.
