Cloud Native Applications with Ballerina

By: Dhanushka Madushan

Overview of this book

The Ballerina programming language was created by WSO2 for the modern needs of developers where cloud native development techniques have become ubiquitous. Ballerina simplifies how programmers develop and deploy cloud native distributed apps and microservices. Cloud Native Applications with Ballerina will guide you through Ballerina essentials, including variables, types, functions, flow control, security, and more. You'll explore networking as an in-built feature in Ballerina, which makes it a first-class language for distributed computing. With this app development book, you'll learn about different networking protocols as well as different architectural patterns that you can use to implement services on the cloud. As you advance, you'll explore multiple design patterns used in microservice architecture and use serverless in Amazon Web Services (AWS) and Microsoft Azure platforms. You will also get to grips with Docker, Kubernetes, and serverless platforms to simplify maintenance and the deployment process. Later, you'll focus on the Ballerina testing framework along with deployment tools and monitoring tools to build fully automated observable cloud applications. By the end of this book, you will have learned how to apply the Ballerina language for building scalable, resilient, secured, and easy-to-maintain cloud native Ballerina projects and applications.

Summary

The automated deployment process is important when building a large application. Cloud native applications are built with small, deployable components. Therefore, the automated deployment process is a must in cloud native architecture. When developers need to deploy some code changes into a production system or testing environment, these code changes should be properly tested before deployment.

In the testing section, we discussed the Ballerina testing framework and writing automated testing. We also learned about mocking functions, different assert functions, and Ballerina's testing life cycle.

We also discussed widely used pipeline deployment tools such as GitHub Actions. GitHub Actions is an ideal platform if you are using GitHub as the source code management platform. GitHub Actions provides multiple plugins to automate the build and deployment pipeline. Ballerina Central plays a key role in building scalable applications by separating a large Ballerina project...
