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

Scaling microservices


At the end of Chapter 12, Scale Microservices with Spring Cloud Components, we discussed two options for scaling either using Spring Cloud components or dockerized microservices using Mesos and Marathon. In Chapter 12, Scale Microservices with Spring Cloud Components, you learned how to scale the Spring Boot microservices using the Spring Cloud components.

The two key concepts of Spring Cloud that we have implemented are self-registration and self-discovery. These two capabilities enable automated microservices deployments. With self-registration, microservices can automatically advertise the service availability by registering service metadata to a central service registry as soon as the instances are ready to accept traffic. Once microservices are registered, consumers can consume newly registered services from the very next moment by discovering service instances using the registry service. In this model, registry is at the heart of this automation.
