This book is based on the modern way of developing a serverless Python-based web or microservices. Being serverless involves a serverless infrastructure provided by the cloud service provider. This book shows how to use Amazon Web Services to implement the serverless infrastructure. Also, it covers the deployment process using Zappa. Zappa eliminates manual intervention, gives you an automated way to proceed deployment, and helps you maintain multiple deployment stages.
This book is for beginner to experienced Python developers who want to understand the way to develop Python web services or microservices on the serverless infrastructure. Experienced Python developers can enhance their skills by learning about the serverless technology and understanding serverless deployment.
Chapter 1, Amazon Web Services for Serverless, covers understanding the basics of AWS Lambda and API Gateway services. Also, the manual process of creating a serverless service by interacting with the AWS console and CLI tool is covered.
Chapter 2, Getting Started with Zappa, explains the concept of the Zappa tool and elaborates the benefits of using Zappa over the manual process of AWS services.
Chapter 3, Building a Flask Application with Zappa, explores basic Flask application development and deployment using Zappa as a serverless application.
Chapter 4, Building a Flask-Based REST API with Zappa, presents the Flask-based RESTful API development and deployment process with Zappa.
Chapter 5, Building a Django Application with Zappa, discusses Django core application development and deploying the application as a serverless over AWS Lambda using Zappa.
Chapter 6, Building a Django REST API with Zappa, focuses on RESTful API implementation using the Django REST framework and the deployment process using Zappa.
Chapter 7, Building a Falcon Application with Zappa, takes you through developing a RESTful API as a microservice using the Falcon framework and the deployment process using Zappa.
Chapter 8, Custom Domain with SSL, explains how to configure a custom domain with Zappa and also covers SSL generation using AWS.
Chapter 9, Asynchronous Task Execution on AWS Lambda, showcases the implementation of asynchronous operations for the time-consuming task of using Zappa.
Chapter 10, Advanced Zappa Settings, familiarizes you with the additional settings of the Zappa tool to enhance the application deployment process.
Chapter 11, Securing Serverless Applications with Zappa, outlines the security aspect of a serverless application over AWS Lambda using Zappa.
Chapter 12, Zappa with Docker, presents application development with AWS Lambda context environment using Docker containerization.

There are a number of text conventions used throughout this book.
CodeInText
: Indicates code words in the text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "Zappa deployment requires the zappa_settings.json
file, which generates the zappa init
command."
A block of code is set as follows:
client = boto3.client('lambda') response = client.invoke( FunctionName='MyFunction', InvocationType='Event' )
When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:
$ curl https://quote-api.abdulwahid.info/daily
{"quote": "May the Force be with you.", "author": "Star Wars", "category": "Movies"}
Any command-line input or output is written as follows:
$ pip install awscli
Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialogue boxes appear in the text like this. Here is an example: "Click on the Create a function
button."
