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.

Exploring the core concepts of the Serverless Framework

Before we can create our first project, we need to know about the bones of the framework, including the terms and definitions that make the experience what it is.

In this section, we'll introduce the terms and point you toward some documentation where you'll find a more complete set of options.

Services

A service is our unit of project. It's our top-level name for the service we are creating and contains all the functions, events, and resources we need for the project. You can build everything you need to in one service, or have multiple services for a single serverless application. It's up to you to define what the delineation is and where the domain...
