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.

Automation with serverless

We're shifting the focus here slightly from the previous sections. Another important area that has been impacted by serverless and event-first thinking is automation.

Groover, Mikell (2014), in Fundamentals of Modern Manufacturing: Materials, Processes, and Systems, described automation as follows:

"The technology by which a process or procedure is performed with minimum human assistance."

In this section, we'll be covering the impact serverless technology has had on automation and how it has enabled a more reactive and event-driven automation approach.

Next, we'll go through the evolution from scripts on a server, to externalizing our configuration, right through to automating our infrastructure's creation.
