Chapter 4, Lightweight Java EE, teaches you how to realize lightweight Java EE applications with a small footprint and minimal third-party dependencies.

Chapter 5, Container and Cloud Environments with Java EE, explains how to leverage the benefits of containers and modern environments, how to integrate enterprise applications, and how this movement encourages productive development workflows.

Chapter 6, Application Development Workflows, covers the key points for fast development pipelines and high software quality, from Continuous Delivery to automated testing and DevOps.

Chapter 7, Testing, as the name suggests, covers the topic of testing, which helps enable you to ensure high quality in software development automated testing with reasonable coverage.

Chapter 8, Microservices and System Architecture, shows the key points of how to design systems after the project and company circumstances, how to construct applications and their interfaces, and when microservice architectures make sense.

Chapter 9, Security, covers how to realize and integrate security concerns in today's environments.

Chapter 10, Monitoring, Performance, and Logging, covers why traditional logging is harmful, how to investigate performance issues, and how to monitor the business and technical aspects of an application.

Appendix, Conclusion, recapitulates and summarizes the contents of the book, including giving advice and motivation.

To execute and perform the code examples given in the book, you will require the following tools configured in your system:

This book is for experienced Java EE developers who aspire to become the architects of enterprise-grade applications, or for software architects who would like to leverage Java EE to create effective blueprints of applications.

In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "The EJB is annotated using @Startup."

A block of code is set as follows:

    @PreDestroy
    public void closeClient() {
        client.close();
    }

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

    private Client client;
    private List<WebTarget> targets;

    @Resource
ManagedExecutorService mes;

In order to increase simplicity and readability, some code examples are shortened to their essence. Java import statements are only included for new types and code parts that are insignificant to the example are omitted using three dots (...).

Any command-line input or output is written as follows:

mvn -v

New terms and important words are shown in bold.
