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 6: Moving on to Serverless Architecture

Serverless architecture is a recent advancement in building systems that run on cloud service providers. Due to the ease of deployment, competitive pricing model, zero Capital Expenditure (CAPEX), and scalability, developers use serverless architecture to build programs on serverless cloud platforms. In this chapter, we will learn about serverless architecture and how to build Ballerina applications with popular serverless platforms such as Azure Cloud and AWS. We will discuss the features provided by each of these platforms to build complex business applications that are running on the cloud.

The following are the topics that we are going to discuss in this chapter:

  • Introducing serverless architecture
  • Developing Ballerina applications with Azure Functions
  • Developing Ballerina applications with AWS Lambda functions

By the end of this chapter, you should be able to create a serverless application by using the...
