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

Reactive microservices


The reactive programming paradigm is an effective way to build scalable, fault-tolerant applications. The reactive manifesto defines basic philosophy of reactive programming.

Note

By combining the reactive programming principles together with the microservices architecture, developers can build low latency high throughput scalable applications.

Microservices are typically designed around business capabilities. Ideally, well-designed microservices will exhibit minimal dependencies between microservices. However, in reality, when microservices are expected to deliver same capabilities delivered by monolithic applications, many microservices have to work in collaboration. Dividing services based on business capabilities will not solve all issues. Isolation and communication between services are also equally important. Even though microservices are often designed around business capabilities, wiring...
