Building Serverless Python Web Services with Zappa

By: Abdulwahid Abdulhaque Barguzar

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.

Installing and configuring Falcon


Configuring the Python application development requires us to set up virtual environments. With the help of a virtual environment, we are going to maintain all required packages. As discussed in Chapter 6, Building a Django REST API with Zappa, the pipenv packing tool maintains all installed packages in a virtual environment and keeps track of versions and dependencies. Let's move on to set up the virtual environment using the pipenv tool.

Setting up the virtual environment

Before starting the actual implementation, we will set up the virtual environment using the pipenv tool. The following is the command to create a new virtual environment:

$ pipenv --python python3.6

Here, I explicitly mentioned the Python version because I use many other Python versions on my system. This command will create a Pipfile as shown here:

[[source]]

url = "https://pypi.python.org/simple"
verify_ssl = true
name = "pypi"
