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

Understanding application requirement over the years


If you go back 10 to 15 years, there were very few internet users, and far less online portals for end users compared to what we have today.

In short, we have become extremely dependent on computers and online computing for personal as well as business use. Every business model is moving towards digitalization. The Prime Minister of India, Mr. Narendra Damodardas Modi has launched a Digital India campaign to ensure that the Government's services are made available to citizens electronically by improved online infrastructure, increasing internet connectivity, and by making the country digitally empowered in the field of technology.

All this implies that the number of internet users is increasing dramatically. According to the Ericsson Mobility Report,

The Internet of Things (IoT) is expected to surpass mobile phones as the largest category of connected devices...
