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.

Developing Ballerina applications with Azure Functions

Azure is a leading cloud application development platform for hosting cloud applications. Azure provides Azure Functions as a serverless solution to build Function as a Service (FaaS) applications. Ballerina provides built-in libraries to create Azure functions. In this section, we will learn how to implement a serverless application with the Ballerina language. We begin by learning about the Azure platform that provides different cloud solutions.

Introducing Azure cloud features

Azure is a cloud service offered by Microsoft that has distributed data centers around the world. Azure provides computing, storage, and network solutions to build cloud applications. Azure pricing is based on the resources you have consumed, in other words, a pay-as-you-go approach. Azure gives you some free credits with the trial subscription to try out their cloud platform.

Azure Portal is the management portal where you can manage Azure Cloud...
