Design Patterns and Best Practices in Java

By: Kamalmeet Singh, Adrian Ianculescu, Lucian-Paul Torje

Overview of this book

Having a knowledge of design patterns enables you, as a developer, to improve your code base, promote code reuse, and make the architecture more robust. As languages evolve, new features take time to fully understand before they are adopted en masse. The mission of this book is to ease the adoption of the latest trends and provide good practices for programmers. We focus on showing you the practical aspects of smarter coding in Java. We'll start off by going over object-oriented (OOP) and functional programming (FP) paradigms, moving on to describe the most frequently used design patterns in their classical format and explain how Java’s functional programming features are changing them. You will learn to enhance implementations by mixing OOP and FP, and finally get to know about the reactive programming model, where FP and OOP are used in conjunction with a view to writing better code. Gradually, the book will show you the latest trends in architecture, moving from MVC to microservices and serverless architecture. We will finish off by highlighting the new Java features and best practices. By the end of the book, you will be able to efficiently address common problems faced while developing applications and be comfortable working on scalable and maintainable projects of any size.

Chapter 8. Trends in Application Architecture

Whenever we start working on an application, the first thing we need to decide is the design or architecture we are going to use. As the software industry has matured in the last few decades, the way we used to design the systems has also changed. In this chapter, we will discuss some of the important architecture trends we have seen in the recent past and which are still relevant to date. We will try to analyze the good, the bad, and the ugly of these architectural patterns and figure out which pattern will be able to solve what type of problem. We will cover following topics in this chapter:

  • What is application architecture?
  • Layered architecture
  • Model View Controller architecture
  • Service-oriented architecture
  • Microservices-based architecture
  • Serverless architecture
