Learn AWS Serverless Computing

By: Scott Patterson

Overview of this book

Serverless computing is a way to run your code without having to provision or manage servers. Amazon Web Services provides serverless services that you can use to build and deploy cloud-native applications. Starting with the basics of AWS Lambda, this book takes you through combining Lambda with other services from AWS, such as Amazon API Gateway, Amazon DynamoDB, and Amazon Step Functions. You’ll learn how to write, run, and test Lambda functions using examples in Node.js, Java, Python, and C# before you move on to developing and deploying serverless APIs efficiently using the Serverless Framework. In the concluding chapters, you’ll discover tips and best practices for leveraging Serverless Framework to increase your development productivity. By the end of this book, you’ll have become well-versed in building, securing, and running serverless applications using Amazon API Gateway and AWS Lambda without having to manage any servers.

Understanding the need for a framework

We need to frame the reasons and benefits of introducing a new tool for our development experience. Adopting a new toolset or application framework is not a decision you make lightly, as it will most likely carry through for the entire life cycle of the project. Before jumping straight in, we should understand the pros and cons of the Serverless Framework first. However, we won't spend too long laboring over this point—we want to jump into creating our first project as soon as possible!

When adopting a framework, keep in mind that, if you're using the console to set up serverless components, you're doing it wrong. This statement largely sums up the sentiment behind adopting a framework. Using the management console to create resources, set configurations, perform uploads, and deployments is not a sustainable approach...
