Zappa is an open source tool that was developed and designed by Rich Jones, founder/CTO of Gun.io (https://www.gun.io/). Zappa was mainly designed to build and deploy serverless Python applications on AWS Lambda and API Gateway.
Zappa is great for deploying serverless Python microservices with frameworks such as Flask and Bottle for hosting large web applications and CMSes with Django. You can also deploy any Python WSGI application as well.
In the previous chapter, we implemented the basic hello world microservice, using AWS Lambda and API Gateway. Zappa automates all these manual processes and gives us a handy tool to build and deploy Python applications.
It's as easy as this:
$ pip install zappa
$ zappa init
$ zappa deploy
As we described earlier, the tradition of web hosting is where the server needs to be always online, listening to HTTP requests...
