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 3: Building Cloud Native Applications with Ballerina

Cloud native is a new concept for developing scalable, reliable, and maintainable cloud applications. There are hundreds of programming languages available out there for building cloud native applications with supported libraries. Ballerina, on the other hand, is explicitly designed to simplify the building of cloud native applications using its own syntax style and lots of different connectors.

In this chapter, we will discuss the unique features provided by Ballerina to build cloud native applications. We will focus on building microservices applications with a popular containerizing application, which is Docker. Also in this chapter, Kubernetes is introduced as the container orchestration platform that handles container deployment. We will go through each of these tools and other supportive tools and build a microservices system with Ballerina's code-to-cloud feature, which helps developers to deploy Ballerina...
