Overview of this book

Getting Started with Spring Microservices begins with an overview of the Spring Framework 5.0, its design patterns, and its guidelines that enable you to implement responsive microservices at scale. You will learn how to use GoF patterns in application design. You will understand the dependency injection pattern, which is the main principle behind the decoupling process of the Spring Framework and makes it easier to manage your code. Then, you will learn how to use proxy patterns in aspect-oriented programming and remoting. Moving on, you will understand the JDBC template patterns and their use in abstracting database access. After understanding the basics, you will move on to more advanced topics, such as reactive streams and concurrency. Written to the latest specifications of Spring that focuses on Reactive Programming, the Learning Path teaches you how to build modern, internet-scale Java applications in no time. Next, you will understand how Spring Boot is used to deploying serverless autonomous services by removing the need to have a heavyweight application server. You’ll also explore ways to deploy your microservices to Docker and managing them with Mesos. By the end of this Learning Path, you will have the clarity and confidence for implementing microservices using Spring Framework. This Learning Path includes content from the following Packt products: • Spring 5 Microservices by Rajesh R V • Spring 5 Design Patterns by Dinesh Rajput

Chapter 8. Implementing Concurrency Patterns

In Chapter 7, Implementing Reactive Design Patterns, we discussed the Reactive Design Pattern and how it fulfills the requirements of today's applications. Spring 5 Framework has introduced the Reactive Web Application Modules for the web application. In this chapter, we will explore some of the Concurrency Design Patterns and how these patterns solve the common problems of the multithreaded application. Spring 5 Framework's reactive modules also provide the solution for the multithreaded application.

If you are a software engineer or are in the process of becoming one, you must be aware of the term concurrency. In geometric properties, concurrent circles or shapes are those shapes that have a common center point. These shapes can differ in dimensions but have a common center or midpoint.

The concept is similar in terms of software programming as well. The term concurrent programming in the technical or programming means the ability of a program...
