Building Microservices with Spring

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

Characteristics of microservices

The microservices definition discussed earlier in this chapter is arbitrary. Evangelists and practitioners have strong, but sometimes, different opinions on microservices. There is no single, concrete, and universally accepted definition for microservices. However, all successful microservices implementations exhibit a number of common characteristics. Therefore, it is important to understand these characteristics rather than sticking to theoretical definitions. Some of the common characteristics are detailed in this section.

Services are first class citizens

In the microservices world, services are first class citizens. Microservices expose service endpoints as APIs and abstract all their realization details. The internal implementation logic, architecture, and technologies, including programming language, database, quality of services mechanisms, and more, are completely hidden behind the service API.

Moreover, in the microservices architecture, there is no...
