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.

The creation and termination of servers

In this chapter, we will learn how to use some third-party tools that will help us in building the required architecture. Like all of the sections in this chapter, the information will be broken down into steps:

  1. The first tool we will be learning about is Ansible. It is a provisioning and orchestrating tool, that helps in automating several parts of an infrastructure. Depending on when you are reading this book, the Ansible project's homepage (https://www.ansible.com/) will look something like this:
  1. The installation process for Ansible is different for different operating systems. The instructions for some popular operating systems are as follows:
    • For Ubuntu:
sudo apt-get update
sudo apt-get install software-properties-common
sudo apt-add-repository ppa:ansible/ansible
sudo apt-get update
sudo apt-get install ansible
    • For Linux...
