Hands-On Design Patterns with Java

2 (1)
By: Dr. Edward Lavieri

Overview of this book

Java design patterns are reusable and proven solutions to software design problems. This book covers over 60 battle-tested design patterns used by developers to create functional, reusable, and flexible software. Hands-On Design Patterns with Java starts with an introduction to the Unified Modeling Language (UML), and delves into class and object diagrams with the help of detailed examples. You'll study concepts and approaches to object-oriented programming (OOP) and OOP design patterns to build robust applications. As you advance, you'll explore the categories of GOF design patterns, such as behavioral, creational, and structural, that help you improve code readability and enable large-scale reuse of software. You’ll also discover how to work effectively with microservices and serverless architectures by using cloud design patterns, each of which is thoroughly explained and accompanied by real-world programming solutions. By the end of the book, you’ll be able to speed up your software development process using the right design patterns, and you’ll be comfortable working on scalable and maintainable projects of any size.

Understanding the microservices pattern

The microservices architectural pattern is used for breaking a system into several smaller services, or microservices, that have limited interdependencies. The benefits of this pattern include the following:

  • The modular nature of the pattern permits individual microservices to be used elsewhere
  • Processing efficiency
  • Easily maintainable code

As illustrated next, there is a central point that interfaces with the microservices that comprise the system. In this example, the central point is the System Interface:

Microservices pattern

The previous diagram also indicates how some microservices can communicate with other microservices. This architectural pattern mandates that the microservices be loosely coupled, so the only true interdependency should be communications.

Software development using the microservices pattern consists of developing...
