Spring Microservices

Overview of this book

The Spring Framework is an application framework and inversion of the control container for the Java platform. The framework's core features can be used by any Java application, but there are extensions to build web applications on top of the Java EE platform. This book will help you implement the microservice architecture in Spring Framework, Spring Boot, and Spring Cloud. Written to the latest specifications of Spring, you'll be able to build modern, Internet-scale Java applications in no time. We would start off with the guidelines to implement responsive microservices at scale. We will then deep dive into Spring Boot, Spring Cloud, Docker, Mesos, and Marathon. Next you will understand how Spring Boot is used to deploy autonomous services, server-less by removing the need to have a heavy-weight application server. Later you will learn how to go further by deploying your microservices to Docker and manage it with Mesos. By the end of the book, you'll will gain more clarity on how to implement microservices using Spring Framework and use them in Internet-scale deployments through real-world examples.

Target architecture

The architecture blueprint shown in the following diagram consolidates earlier discussions into an architectural view. Each block in the diagram represents a microservice. The shaded boxes are core microservices, and the others are supporting microservices. The diagram also shows the internal capabilities of each microservice. User management is moved under security in the target architecture:

Each service has its own architecture, typically consisting of a presentation layer, one or more service endpoints, business logic, business rules, and database. As we can see, we use different selections of databases that are more suitable for each microservice. Each one is autonomous with minimal orchestration between the services. Most of the services interact with each other using the service endpoints.

Internal layering of microservices

In this section, we will further explore the internal structure of microservices. There is no standard to be followed for the internal architecture...
