- Amazon API Gateway is a service to connect with other AWS services. API Gateway provides a RESTful application interface for mobile and web applications to connect with other AWS services. In our case, Zappa configured the API Gateway interface with proxy requests to invoke AWS Lambda.
Zappa performs the deployment operation based on the
zappa_settings.json
file configuration. Zappa uses thefunction_name
to point the Flask application object in order to configure the application on AWS Lambda and API Gateway.

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.
