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.

Adding Amazon API Gateway

In this chapter, we're going to add Amazon API Gateway to the mix and talk about why this service is such a good fit for Lambda. By adding an API gateway to our Lambda solutions, we are also introducing some features and benefits that will help to make our architectures production-ready. These features are centered around API management, which can help with things such as throttling and quota management, monetization of your APIs, and added security functionality. One of the additional benefits of using Amazon API Gateway over other options is its native integration with Lambda along with many other integrations in the AWS ecosystem.

We'll go over some of these features and then build on the knowledge learned from the previous chapter to explain how to create an API backed by a Lambda function.

We'll cover the following topics:
