Cloud-Native Applications in Java

By: Andreas Olsson, Ajay Mahajan, Munish Kumar Gupta, Shyam Sundar S

Overview of this book

Businesses today are evolving so rapidly that they are resorting to the elasticity of the cloud to provide a platform to build and deploy their highly scalable applications. This means developers now are faced with the challenge of building build applications that are native to the cloud. For this, they need to be aware of the environment, tools, and resources they’re coding against. If you’re a Java developer who wants to build secure, resilient, robust, and scalable applications that are targeted for cloud-based deployment, this is the book for you. It will be your one stop guide to building cloud-native applications in Java Spring that are hosted in On-prem or cloud providers - AWS and Azure The book begins by explaining the driving factors for cloud adoption and shows you how cloud deployment is different from regular application deployment on a standard data centre. You will learn about design patterns specific to applications running in the cloud and find out how you can build a microservice in Java Spring using REST APIs You will then take a deep dive into the lifecycle of building, testing, and deploying applications with maximum automation to reduce the deployment cycle time. Gradually, you will move on to configuring the AWS and Azure platforms and working with their APIs to deploy your application. Finally, you’ll take a look at API design concerns and their best practices. You’ll also learn how to migrate an existing monolithic application into distributed cloud native applications. By the end, you will understand how to build and monitor a scalable, resilient, and robust cloud native application that is always available and fault tolerant.

Chapter 1. Introduction to Cloud-Native

The advent of cloud computing and the ubiquity of mobile devices have led to the rise of consumer-facing companies (such as Amazon, Netflix, Uber, Google, and Airbnb) that have redefined the entire customer experience. These companies have built their applications (both web and mobile interfaces) on the cloud, using features or services that allow them to scale up or down based on demand, be available at all times, and be ready to handle failures at all levels.

Traditional enterprises are looking at these consumer-facing companies and want to adopt some of their best practices. They do this to help scale up their rapidly evolving enterprise applications, allowing them to take advantage of the elasticity and scalability of the cloud.

Before we dive deep into cloud-native, let's see what this chapter holds. We will cover the following topics in this chapter:

  • Why go cloud-native?
  • What is cloud-native?
  • Intro to the 12-factor app
  • Why move from monolithic applications to distributed microservice-based applications?
  • The advantages of building a distributed microservice-based application
