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.

AWS platform

Amazon AWS was the pioneer of cloud computing, and has been expanding its cloud offerings ever since to maintain its leadership position. The following diagram gives an indicative list of services offered by the AWS platform for application developers:

This is just an indicative list and by no means an exhaustive list; refer to the Amazon AWS portal for a complete list.

The categories are as follows:

  • Infrastructure: This is probably the core of the AWS platform that enables it to provide a plethora of other services. These can be further classified into:
    • Compute: Services such as EC2, Lambda, ECS, and ELB. We will be demonstrating the deployment of our sample application using primarily compute services, but it is relatively easy to tie them up with the other services offered by AWS.
    • Storage: Services such as S3, EBS, and CloudFront.
    • Networking: Services such as VPC, Route53, and DirectConnect.
  • Application: These services can be used as components to build and support applications...
