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.

Section 2: Building Microservices with Ballerina

This second section focuses on building microservices with the Ballerina language. In this section, we will go through the architectural concepts of microservice architecture and how we can implement a real-world scenario with the Ballerina language.

First, we will discuss the cloud native features provided by the Ballerina language, including Ballerina service syntaxes, remote methods, JSON/XML data type support, and the deployment of Ballerina artifacts on microservice architecture. We will discuss Docker and Kubernetes to deploy and orchestrate a Ballerina program as containers.

Next, we will discuss inter-process communication and messaging between services in a microservice architecture. We will discuss both synchronous and asynchronous communication protocols and how we can implement those with the Ballerina language.

Finally, we will understand using databases with the Ballerina language in a microservice environment...
