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

Benefits of containers


We have already seen many benefits of containers over VMs. This section will explain the overall benefits of containers beyond the benefits of VMs.

Some of the benefits of containers are summarized as follows:

  • Self contained: Containers package essential application binaries and its dependencies together to make sure that there is no disparity between different environments, such as development, testing, or production. This promotes the concept of the Twelve-Factor applications and the concept of immutable containers. The Spring Boot microservices bundles all required application dependencies. Containers stretch this boundary further by embedding the JRE and other operating system-level libraries, configurations, and so on, if any.
  • Lightweight: Containers, in general, are smaller in size with a lighter footprint. The smallest container, Alpine, has a size of only less than 5 MB. The simplest Spring Boot microservices packaged with an Alpine container with Java 8 will...
