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.

The benefits of containers


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

  • Self-contained: Containers package the essential application binaries and their dependencies together to make sure that there is no disparity between different environments such as development, testing, or production. This promotes the concept of Twelve-Factor applications and that of immutable containers. Spring Boot microservices bundle all the required application dependencies. Containers stretch this boundary further by embedding JRE and other operating system-level libraries, configurations, and so on, if there are any.

  • Lightweight: Containers, in general, are smaller in size with a lighter footprint. The smallest container, Alpine, has a size of less than 5 MB. The simplest Spring Boot microservice packaged with an Alpine container with Java 8 would only come to around 170 MB in size. Though the size...
