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.

JCP and participation

The Java Community Process (JCP) defines the standards that make up the Java SE and EE platforms, including the Java EE umbrella standard itself. The individual standards are defined as Java Specification Requests (JSR), each forming so-called Expert Groups, consisting of experts and companies involved in enterprise software.

The idea is to standardize technology that has proven itself well in real-world projects. The experience of companies and individuals from these real-world projects is brought together to form vendor-independent Java enterprise standards.

It's highly advisable for both companies and individuals to participate in the JCP. It provides the ability to form the standards and the future of Java technology as well as to gain knowledge in this technology. The open processes of the JCP enable developers to get insight about how the future versions of Java EE will look.

Individuals and companies can also follow the standardization processes, even if they don...
