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.

Chapter 10: Building a CI/CD Pipeline for Ballerina Applications

Cloud applications are generally larger in size and complex in terms of deployment. Regardless of whether the system is complex or simple, automating the system has multiple advantages. Software that has been started on a small scale can be scaled up to complex code that can be distributed over several services.

Having a manual process to deploy an application can become a nightmare when it comes to such a large system. On the other hand, a single adjustment to the system could break down the entire production in a few milliseconds. Continuous Integration (CI) and Continuous Delivery (CD) pipe systems in DevOps culture offer an ideal way to maintain larger cloud applications.

In this chapter, we will discuss the features provided by the Ballerina language along with other popular tools to implement CI/CD pipelines for cloud native applications. We will discuss freely available CI/CD pipeline development tools that...
