Overview of this book

Serverless applications are becoming very popular these days, not just because they save developers the trouble of managing the servers, but also because they provide several other benefits such as cutting heavy costs and improving the overall performance of the application. This book will help you build serverless applications in a quick and efficient way. We begin with an introduction to AWS and the API gateway, the environment for serverless development, and Zappa. We then look at building, testing, and deploying apps in AWS with three different frameworks--Flask, Django, and Pyramid. Setting up a custom domain along with SSL certificates and configuring them with Zappa is also covered. A few advanced Zappa settings are also covered along with securing Zappa with AWS VPC. By the end of the book you will have mastered using three frameworks to build robust and cost-efficient serverless apps in Python.

Amazon Web Services for Serverless

In this chapter, we are going to learn about Amazon Web Services for managing a serverless infrastructure. We will be exploring the AWS workflow to create a serverless application. We will learn about the manual process for creating a basic serverless application and an automated process using the AWS CLI (command line interface).

Topics we will cover in this chapter include:

  • Transitioning from the traditional server to serverless
  • Getting started with AWS Lambda
  • How AWS Lambda works
  • Executing a Lambda function
  • Creating Lambda triggers
  • Creating a serverless RESTful API
  • AWS Lambda interaction by the AWS CLI
