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.

Ballerina cloud native syntaxes and features

Ballerina includes a rich collection of syntaxes and features that are specially designed for cloud native applications. Ballerina has its own way of defining services, which is the basic building unit of microservices applications. You can handle data coming in and going out with JSON and XML data types that are natively supported by the Ballerina language. In the upcoming sections, we will discuss these features in more detail with code samples. First, we'll look at the role of Ballerina in cloud native applications.

The role of Ballerina in cloud native architecture

Ballerina is an open source, general-purpose programming language built specifically to program distributed systems running as services. Ballerina offers a range of libraries and tools to build cloud native applications easily. The Ballerina language is compatible with all the factors of the twelve-factor application, which is essential in building cloud native...
