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.

Death of the monolith


The PSS application was performing well, successfully supporting all business requirements as well as the expected service levels. The system had no issues in scaling with the organic growth of the business in the initial years.

The business has seen tremendous growth over a period of time. The fleet size increased significantly, and new destinations got added to the network. As a result of this rapid growth, the number of bookings has gone up, resulting in a steep increase in transaction volumes, up to 200 - to 500 - fold of what was originally estimated.

Pain points

The rapid growth of the business eventually put the application under pressure. Odd stability issues and performance issues surfaced. New application releases started breaking the working code. Moreover, the cost of change and the speed of delivery started impacting the business operations profoundly.

An end-to-end architecture review was ordered, and it exposed the weaknesses of the system as well as the...
