Java EE 8 Design Patterns and Best Practices

By: Rhuan Rocha, Joao Carlos Purificação

Overview of this book

Patterns are essential design tools for Java developers. Java EE Design Patterns and Best Practices helps developers attain better code quality and progress to higher levels of architectural creativity by examining the purpose of each available pattern and demonstrating its implementation with various code examples. This book will take you through a number of patterns and their Java EE-specific implementations. In the beginning, you will learn the foundation for, and importance of, design patterns in Java EE, and then will move on to implement various patterns on the presentation tier, business tier, and integration tier. Further, you will explore the patterns involved in Aspect-Oriented Programming (AOP) and take a closer look at reactive patterns. Moving on, you will be introduced to modern architectural patterns involved in composing microservices and cloud-native applications. You will get acquainted with security patterns and operational patterns involved in scaling and monitoring, along with some patterns involved in deployment. By the end of the book, you will be able to efficiently address common problems faced when developing applications and will be comfortable working on scalable and maintainable projects of any size.

Summary


In this chapter, we explored operational patterns, performance and scalability patterns, and management and monitoring patterns. We also looked at why we should use these operational patterns and how to evaluate the best use for them.

On the topic of performance and scalability patterns, we looked at performance and scalability patterns such as cache-aside, CQRS, event sourcing, index table, materialized view, and sharding. Then, we explained each pattern's concept, what the benefits of it are, and when to implement it. We are now familiar with the techniques required for increasing the performance of an enterprise application, as well as how to make the application scalable.

On the topic of management and monitoring patterns, we explored management and monitoring patterns such as ambassador patterns, health endpoint monitoring patterns, and external configuration store patterns. We explained each pattern's concept, what the benefits of it are, and when to implement it. We are now...
