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.

About the authors

Ajay Mahajan is a Distinguished Member of Technical Staff (DMTS) at Wipro Technologies, and currently is in role of Chief Technologist of Retail vertical. In his current role, he helps customers adopt cloud-native and digital architecture for next-generation retail applications. He worked with retail and banking clients in Europe and USA on large-scale mission-critical systems. He has seen the evolution of enterprise Java from the Netscape Application Server to servlets/JSP, JEE, Spring, and now the cloud and microservices during the course of 19 years of working on Java platform.

A lot of ideas, best practices, and patterns for this book originated from our work in Emerging Technologies, which was spearheaded by Aravind Ajad Yarra. My special thanks goes to Shyam (coauthor), who is the most talented technical person I have come across. A big thanks to Munish for brainstorming the structure and content of the book. My thanks to Hari Burle, whose encouraging words and guidance helped me keep my focus on the book.

Munish Kumar Gupta is a lead system architect with Visa. Based in Bangalore, India, his day-to-day work involves solution architectures for applications with stringent non-functional requirements, application performance engineering, managing application infrastructure, and exploring the readiness of cutting-edge, open source technologies for enterprise adoption. He is the author of Akka Essentials. He is very passionate about software programming and craftsmanship. He blogs about technology trends, application performance engineering, and Akka.

I have to start by thanking my wife, Kompal. She urged me to keep writing, and here I am with my second book. Thanks to everyone on the Packt team who helped me so much. A special mention to Zeeyan, Nitin, and Romy.

Shyam Sundar is a senior architect with Wipro Technologies based in Bangalore. He is part of the Emerging Technologies Architecture group within Wipro. He is responsible for helping teams adopt new and emerging technologies in their projects. He focuses primarily on the client side and cloud technologies. He is a lifelong learner who cares deeply about software craftsmanship. He is constantly experimenting with new tools and technologies to improve the development experience.

I have to first thank my coauthors, Ajay and Munish, for taking me along on this incredible journey with them. For someone who is more used to expressing themselves with code rather than words, both Ajay and Munish gave a lot of thoughtful pointers on how to structure the content and simplify the concepts. I must also thank my boss, Aravind Ajad Yarra, for his continued support and encouragement.
