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.

The Evolution of Compute

You're here to learn a new skill, to expand your understanding of new ways of compute, and to follow along with the examples in this book to gain practical experience. Before we begin, it would be helpful to know a bit of the history and context behind why serverless exists. This chapter will explain the progression of thinking from the humble data center through to the new goalposts of serverless.

We'll learn how the placement of physical hardware has evolved from the perspective of the infrastructure engineer and developer, and how the different stages have allowed us to achieve new layers of compute abstraction. The evolution of these factors has also driven new ways of structuring software, and we will explore some of the reasons behind this.

The following topics will be covered in this chapter:

  • Understanding enterprise data centers
  • Exploring the units of compute
  • Understanding software architectures
  • Predicting what comes next

We will delve in these topics one by one and learn how each aspect functions.
