Building Serverless Applications with Python

Overview of this book

Serverless architectures allow you to build and run applications and services without having to manage the infrastructure. Many companies have adopted this architecture to save cost and improve scalability. This book will help you design serverless architectures for your applications with AWS and Python. The book is divided into three modules. The first module explains the fundamentals of serverless architecture and how AWS lambda functions work. In the next module, you will learn to build, release, and deploy your application to production. You will also learn to log and test your application. In the third module, we will take you through advanced topics such as building a serverless API for your application. You will also learn to troubleshoot and monitor your app and master AWS lambda programming concepts with API references. Moving on, you will also learn how to scale up serverless applications and handle distributed serverless systems in production. By the end of the book, you will be equipped with the knowledge required to build scalable and cost-efficient Python applications with a serverless framework.

Setting up integration

As we now understand how the AWS API Gateway service works at a basic level, we will move on to use that knowledge for building an end-to-end project which involves deploying a completely serverless API.

In this section, we will be building and deploying a completely serverless API function from scratch, along with learning the internals and other implementation details of the AWS Lambda—AWS API Gateway integrations. We will be building the serverless API step-by-step. So, follow along with the steps in this order. The procedure is as follows:

  1. Firstly, we will start by creating a new API. This can be done via the Lambda console which looks like this:
  1. Once you have clicked on the +Create API button, you will be redirected to the API creation wizard, where you will be asked to enter the name and description of the API you are intending to build...
