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.

Summary

There we have it. We've added Amazon API Gateway to AWS Lambda and other services to implement real-world serverless API architectures. Covering security at the start was important because, without properly securing our services, we can't safely offer functionality to our customers and consumers. We also learned about some of the API management functionality that Amazon API Gateway can bring to our solutions; these are key when we're planning a production implementation and when we want to expose our compute service via a RESTful API. Finally, we created an API of our own using the console and the CLI. Later on, we will show you an application framework that will make creating and maintaining APIs much easier.

In the next chapter, we going to be delving more deeply into more components of serverless architectures. We'll explore some examples of other...
