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.

Introducing Amazon API Gateway

Amazon API Gateway is another component in the serverless arsenal from AWS. It is used to create and manage RESTful and WebSocket APIs in front of your backend functionality.

In this section, we'll dig into the features and benefits, see what our deployment options are, and review some common use cases.

Serverless APIs

There are several reasons for using an API Gateway, and the first is to abstract the implementation of your application or service away from the client. This is to allow you to have greater flexibility in how the business logic and processing are built, and so that the client doesn't have to understand the underlying data structures or storage layer.
