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

Microservices on Cloud

One of the capabilities mentioned in the microservices capability model is the use of the Cloud infrastructure for microservices. Earlier in this chapter, we also explored the necessity of using Cloud for microservices deployments. So far, we have not deployed anything to the Cloud. Once we have many microservices, it will be hard to run all of them on the local machine.

In the rest of this book, we will operate using AWS as the Cloud platform for deploying the BrownField PSS microservices.

Installing Docker on AWS EC2

In this section, we will install Docker on the EC2 instance. Follow these steps to install Docker.

This example assumes that you are familiar with AWS and an account has already been created on AWS:

Follow these steps to set up Docker on EC2:

  1. Launch a new EC2 instance. In this case, if we have to run all instances together, we may need a large instance. The example uses t2.large.


In this example, the following Ubuntu AMI is used. Ubuntu Server 16.04 LTS...
